Connecticut cornerback Byron Jones made history at the 2015 combine, with an unbelievable broad jump of 147 inches. And the video was every bit as impressive as it sounds. Keep in mind that no other player in combine history has ever even hit the 140 inch mark, giving Jones a full 8″ lead on every other broad jump ever recorded in Indianapolis.

On the other hand, Alvin “Bud” Dupree did something special, too. Remember, the Kentucky outside linebacker weighed in at 269 pounds, and he managed to jump 138 inches. In combine history, no other player over 260 pounds has jumped more than 129 inches; lower the weight to over 250 pounds, and the best mark after Dupree is 131 inches. So the Wildcats edge rusher was really in a class of his own, too.

There were 249 prospects in Indianapolis who performed in the broad jump. I performed a regression analysis using weight and height as my inputs, since both variables were highly significant in predicting the broad jump. Here is the best-fit formula: [continue reading…]

As a general rule, shorter and heavier guys tend to dominate the bench press. When I looked at this last year, the best-fit formula to predict the number of reps of 225 a prospect could achieve was:

Expected BP = 30.0 – 0.560 * Height + .1275 * Weight

What does that mean? All else being equal, if Prospect A is 7 inches shorter than Prospect B, we would expect Prospect B to produce about 4 more reps than Prospect A. And for every eight pounds of body weight a player has, we would expect one additional rep out of that prospect.

Which brings us to Clemson outside linebacker Vic Beasley. Standing 6’3 and “only” 246 pounds, Beasley doesn’t exactly fit the profile of a bench pressing machine. But in Indianapolis, he pumped out an incredible 35 reps, tied for the third most at the combine (no other player under 300 pounds had even 33 reps). Given his height and weight, the formula above would project Beasley for 19.4 reps, which means he exceeded expectations by a whopping 15.6 reps. No other player came close to exceeding expectations to such a significant degree.

One of the biggest headlines from the combine were the jumps from Byron Jones, a cornerback from Connecticut. Most impressive was his broad jump, which was not only 8 inches better than everyone else in Indianapolis, but also 8 inches better than anyone else in combine history. More on his broad jump in a future post, but Jones’ 44.5″ vertical too shabby, either: it was the best since 2009, when Ohio State and eventual Chiefs safety Donald Washington jumped 45 inches (a feat later matched by one other player at this year’s combine).

But Jones didn’t have the most impressive vertical at the combine, because at 199 pounds, there’s an expectation that he would do fairly well in that drill.  Given his weight, we would expect Jones to jump about 35.5 inches, based on the best-fit formula derived here, and defined below:

Expected VJ = 48.34 – 0.0646 * Weight

One way to think of that formula is that for every 15.5 pounds of player weight, the expectation on the vertical is one fewer inch.  So at 230 pounds, the expectation would be 33.5 inches.  Which brings us to Alvin “Bud” Dupree, whom we lauded yesterday for the top performance in the 40-yard dash.  At 269 pounds, he would be expected to jump roughly 31.0 inches.  Instead, the Kentucky edge rusher jumped a whopping 42.0 inches — or 11.0 inches over expectation — making it the best weight-adjusted performance of any player in Indianapolis.

Bud Dupree Ran The Top Weight-Adjusted 40 At 2015 Combine

Last year, I looked at various data from the NFL combine and tried to put the results from some of the drills in perspective. Let’s do that again with the 40-yard dash, with data courtesy of courtesy of NFLSavant.com.

The best-fit formula to project a 40-yard dash time, given a prospect’s weight, is:

Expected 40 Time = 3.433 + 0.00554 * Weight

Alvin “Bud” Dupree, an outside linebacker from Kentucky, weighed in at 269 pounds at the combine, giving him an expected 40 time of 4.92. But in Indianapolis, he ran the dash in just 4.56 seconds, meaning he exceeded expectations by an incredible 0.36 seconds. That was the top time of 2015, and would have been the second best in 2014 behind only to Jadeveon Clowney.

The full results from the Combine this year, below: [continue reading…]

College Football Season Recap

The college football regular season is over. You can view the SRS ratings for each team here, and the single-game SRS ratings from each game involving an FBS team here. That list is sorted by the best single-game performances of the year, and Ohio State’s 59-0 thrashing of Wisconsin in the Big 10 Championship Game takes the top prize there. But today I thought it would be fun to go back and look at some of the most unusual performances of the year.

Biggest Upset: Northwestern State 30, Lousiana Tech 27

Northwestern State is an FCS school with a rating of just 23.7. Louisiana Tech is actually pretty good, finishing 8-5 and 37th in the SRS with a rating of 43.4. Given that the game was in Louisiana, we would put Northwestern State as 23-point underdogs, but on September 20th, they pulled the shocking upset. Although it was not the most noteworthy upset of the day, because….

Biggest Upset involving a Power 5 school: Indiana 31, Missouri 27

Missouri won the SEC East, although the Tigers were not a great team, finishing with a 48.9 SRS rating. Of course, Indiana is kind of terrible: the Hoosiers began the year 0-7 in Big Ten play before edging by Purdue in the season finale. Given that the game was in Columbia and that Indiana finished with a 31.4 SRS rating, Missouri should have won by 20.4 points. Instead, Indiana pulled the shocking upset, and gave SEC haters something to crow about.

The table below shows the 25 biggest upsets of the year: the Virginia Tech/Ohio State game slides into the top five, as does this year’s Bedlam game, which flew a bit under the radar given what else was going on in college football last week. For each team, I’ve listed their SRS rating and their opponent’s SRS rating, along with the difference between the two teams’ ratings after taking into account home field.

Best Bowls

The Sugar Bowl, featuring Alabama and Ohio State, checks in as the best game of Bowl season, as measured by the average ratings of the two teams. The Crimson Tide have the best SRS rating, while Ohio State has the 5th highest rating.

The other playoff matchup comes in the Rose Bowl, but Florida State’s poor rating actually drops them game to #4 behind the Peach Bowl (TCU/Ole Miss) and even the Cotton Bowl Classic (Baylor/Michigan State).

The worst game? That’s South Alabama and Bowling Green in the new Camelia Bowl. Yes, the inaugural game of a new Alabama Bowl game featuring two six-loss teams will kick off at 9:20 on the opening night of Bowl season. Make sure you have your schedule cleared for that one.

Biggest Mismatches

Marshall and Northern Illinois face off in a game that, on the surface, appears to be a very good one. Marshall is 12-1 and a legitimately good team. On the other hand, while Northern Illinois is 11-2, a bunch of close wins against MAC teams doesn’t make UNI a good team. The Huskies lost by 38 against Arkansas and by 17 at home against a bad Central Michigan team. Northern Illinois is 12.3 points worse than Marshall in the SRS, which makes traveling to Boca Raton even more depressing.

Arkansas/Texas, Georgia/Louisville, and Louisiana Tech/Illinois are all 10-point mismatches, too. Of course, Bowl season has a habit of deviating from the regular season script, so don’t blame me when all the underdogs win. According to Vegas, the Foster Farms Bowl at Levi’s Stadium in Santa Clara is the most lopsided matchup. One reason for that: Stanford is the de facto host here, and the Cardinal are 14 point favorites against Maryland. [continue reading…]

The college football regular season is over. Florida State ends the year as the only unbeaten team, even if the defining characteristic of the Noles’ season was their inability to ever earn any style points. FSU ends the regular season a mind-boggling 3-10 against the spread, which is all you need to know about how the team played relative to expectations on a weekly basis.

Most agree that Alabama and Oregon are the top two teams in the country; the SRS agrees with the consensus! The Crimson Tide have emerged with an SRS rating of 62.0, with the Ducks narrowly behind at 61.5.  The Seminoles are down at 15 in the SRS, which is unsurprising to regular readers.  The SRS is a predictive system, like Las Vegas; this implies that Florida State would be an underdog to all the top teams, which is hard to argue against.

Of course, FSU will take one of the four golden tickets, as will Alabama and Oregon.  The fourth spot in the first ever college football playoff will come down to TCU, Ohio State, or Baylor.  The SRS is not necessarily a great way to decide which team should advance — after all, that should be based more on resume than on best team — but it can be instructive to look at the ratings.  In this case, those three teams check in at #3, #5, and #6.

As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs. Some more playoff thoughts about the jump:

The Baylor/TCU Question

Today, TCU will finally play Iowa State, the worst team in the Big 12, and Baylor will finally play Kansas State, the best team in the Big 12 after Baylor and TCU. At that point, both the Horned Frogs and Bears will have faced each other and nine common opponents. [1]In addition to the remaining 8 teams in the Big 12, both TCU and Baylor beat SMU in nonconference play. The chart below shows how each team fared against those ten common opponents, treating Baylor/TCU as one team.

On the X-Axis is each opponent, in (roughly) descending order from left to right in terms of strength. For both Baylor and TCU, the other team was its toughest opponent, while Iowa State and SMU were the two easiest opponents both teams faced. On the Y-Axis is the home field adjusted margin of victory. Of note: TCU lost by 3 to Baylor, but the game was played in Waco, so both teams get a 0 for that game. TCU is represented by the purple dot below, with Baylor’s results displayed in green:

College Football Rivalry Weekend

A couple of quick notes on rivalry weekend, using the latest SRS ratings. All rankings come from the College Football Playoff.

#15 Auburn at #1 Alabama (-8.5)

In the SRS, Alabama is first overall with a rating of 61.7; Auburn is 7th overall, which may surprise some folks, courtesy of a 57.5 rating. Given that the game is in Tuscaloosa, that would imply a spread of -7.2, not too far off of the 8.5-point line. Auburn is probably a top ten team in Vegas’ ratings as well, so this Iron Bowl may be closer than some experts think.

Florida at #2 Florida State (-7.5)

Sure, FSU is ranked #2 in the country while Florida is an unranked and disappointing 6-4. But the teams are pretty close in the SRS, with the Seminoles at #17 (51.6) and the Gators at #24 (49.4). We would expect the spread in Tallahassee to be FSU -5.2, again, closer than you might think. A Florida upset would be surprising, but not shocking.

#3 Oregon at Oregon State (+19.5)

This one should not be all that close: Oregon has a 60.3 in the SRS, which would imply a 23.8-point spread over the Beavers (33.5). Don’t believe anyone who invokes the phrase “throw the records out” when they preview this game.

#4 Mississippi State at Ole Miss (+2.5)

The SRS narrlowly prefers Ole Miss despite the worse record: the Rebels should be 3.6-point favorites given the ratings of each team. This game is a true toss up, but also one where the spread is about 6 points off of the SRS.

#5 TCU at Texas (+5)

Given the records for each team — 9-1 for the Horned Frogs, 6-5 for the Longhorns — you might be surprised that the spread is just five points. TCU has an SRS rating of 59.4, while Texas is down at 44.4. We would expect TCU to be 12-point favorites, so the spread being off by a full touchdown here is an eye-opener. On the other hand, Texas has been playing better of late, so the upset watch is on in Austin.

Michigan at #6 Ohio State (-21)

This is one spread that lines up perfectly with the SRS: Ohio State is 17.7 points better than Michigan on a neutral field, so being three touchdown favorites at home makes sense.

#7 Baylor vs. Texas Tech (+24.5)

Baylor (59.5) is 4th overall in the SRS, while the Red RAiders are down at #82 (32.4). That would imply a home spread of Baylor -30, so I guess Vegas views this game as ever-so-slightly more competitive than the SRS.

Stanford at #8 UCLA (-5.5)

UCLA has an SRS of 53.5, good enough for 15th overall. Stanford is a competitive 6-5, but the Cardinal’s 46.6 rating puts them down at 32nd in the SRS. Given that the game is in LA, a 10-point spread would make sense. The Bruins have a very uphill battle to crack the top 4, but a win over Stanford is the first domino that must fall (well, a Texas win tonight would help, too).

Comparing the Pac-12 South and the SEC West

The Pac-12 South now has 5 teams in the top 20 of the college football playoff rankings: UCLA at #9, Arizona State at 13, Arizona at 15, Utah at 17, and USC at 19. All five teams also appear in the top 25 of the AP Poll, with 2-8 Colorado being the only Pac-12 South team left out in the cold. Meanwhile, the SEC West has lost some of its luster after a disastrous week 11: only four of seven SEC West teams are in either sets of rankings, with LSU, Texas A&M, and Arkansas now unranked.

Simple math tells us that placing 5 out of 6 teams in the top 25 is more impressive than 4 out of 7; on the other hand, 25 is a pretty arbitrary cut-off point. Three SEC West teams appear in the top 8 of the playoff rankings, compared to zero Pac-12 teams. The same is true of the AP Poll, where Alabama, Mississippi State, and Ole Miss are all ahead of #11 UCLA, the highest-ranked Pac-12 South squad. If you were to combine the two divisions, the rankings would look something like this:

  • SEC West (Alabama)
  • SEC West (MSU)
  • SEC West (Ole Miss)
  • P-12 South (UCLA)
  • P-12 South (Arizona State)
  • P-12 South (Arizona)
  • SEC West (Auburn)
  • P-12 South (Utah)
  • P-12 South (USC)
  • SEC West (LSU)
  • SEC West (Texas A&M)
  • SEC West (Arkansas)
  • P-12 South (Colorado)

From that vantage point, the Pac-12 South doesn’t look so hot: the #1 team in the SECW is ahead of the #1 team in the P-12S, the #2 is ahead of #2, #3 is ahead of #3, #4 is ahead of #4, and the 6th and 7th best teams are ahead of the 6th best team.  The only advantage the Pac-12 South has, perhaps, is that it’s 5th best team — USC — has a slightly better resume than that of the 5th best team — LSU — in the SEC West.

But all of the above is based solely on the rankings.  When you look deeper at each team’s season, the differences become more stark.

For starters, Colorado is a terrible team, while the SEC West boasts no bad teams.  Arkansas is 5-5, courtesy of a 1-4 record in the SEC West and a loss to Georgia; on the other hand, the Razorbacks also blew out Alabama-Birmingham, Texas Tech, and Northern Illinois, three teams that are very comparable to Colorado.  Against Alabama, Georgia, and Mississippi State — three top ten teams — the Hogs are 0-3 but with an average margin of defeat of just 7 points.

If we want to just look at the quality teams in each division, then, we are looking at 5 teams in the Pac-12 South and 7 in the SEC West.  It’s probably unfair to do such a comparison to the SEC West, but let’s do it anyway.

Head to Head

Let this be a good reminder of how frustrating college football analysis can be: not only have there been zero games this year between the SEC West and the Pac-12 South, but there have been no interconference games at all between the SEC and the Pac-12. In fact, there’s only one team in the country that’s even played a team from both divisions: Memphis, which lost 24-3 in Oxford and 42-35 at the Rose Bowl.

Losses

The seven SEC West teams have just three losses in non-division play this year, which is three times as many as it had week ago.  Those three loses were by Arkansas and Auburn to a very good Georgia team, and by Texas A&M to a pretty good Missouri squad.

The five Pac-12 teams have five interdivision losses: UCLA and Utah both lost to an excellent Oregon team, which is pretty understandable.  From there, though, the wheels fall off the track pretty quickly: USC lost to 6-4 Boston College, Arizona State lost to a 4-6 Oregon State, and Utah lost at home to a 3-7 Washington State team.  The Utes led 21-0 in that game and 27-14 in the 4th quarter, but wound up losing 28-27 in one of the more inexplicable losses of the year.

Judged solely by losses, the SEC West is the far superior division.  The biggest wart is probably Auburn’s blow out loss against UGA, but Utah also lost by 24 at home to Oregon, so the Pac-12 South can’t say it has avoided blow outs, either.

Wins

The most impressive non-division win from either set of schools this year probably belongs to the Pac-12: [1]At least if you exclude Margin of Victory. If you include that, one could make the case for the 34-3 win by Ole Miss over Tennessee, which registered a whopping 79 on the SRS, the 9th best result … Continue reading Arizona’s 7-point win in Eugene over the Ducks. After that, though, one could argue that the next seven best wins came from the SEC West.

Close calls aside, there’s nothing to criticize about when it comes to wins on the road against Kansas State (Auburn) or on a neutral field against Wisconsin (LSU). Those two teams a combined 15-2 in all other games. A neutral site victory against 6-5 West Virginia (Alabama) counts for something, too.  Tennessee and Florida are both inconsistent SEC East teams, but (1) the SRS has both teams in the top 25, and (2) both teams are in the top 30 of Sagarin’s pure predictor ratings.  The Football Outsiders ratings have both squads slightly lower, but in any event, SEC West teams have registered a 4-0 record against those two teams.

What about the Pac-12? After Oregon, the next best win is either: (1) any of the wins by ASU, Southern Cal, or Utah against Stanford, (2) Arizona State against Notre Dame, or (3) UCLA against Texas.  Those are all solid wins, but those five are pretty comparable to the five against West Virginia, Tennessee, and Florida.

Conclusion

The Pac-12 South now has five top 25 teams, but the number 25 is a pretty arbitrary bench mark. The SEC West, despite having an additional team, is stronger top to bottom. The SEC West has entirely avoided losses to bad teams, something the Pac-12 South can’t quite represent. And when it comes to non-division wins, it’s a close call, but the SEC West probably has the better case to be made. The Pac-12 South remains a great division, but it’s clear that even after a rough week 11, the SEC West is still the top division in college football.

Checkdowns: College Football QB ANY/A, 2014

Adjusted Net Yards per Attempt is the basic measure I use to measure quarterback performance. ANY/A, of course, is calculated as follows:

(Passing Yards + 20*PassingTDs – 45*INTs – SackYardsLost) / (Sacks + Attempts)

Finding college football sack data is notoriously challenging, but ESPN does at least list sack numbers (but not sack yardage lost) for quarterback. But if we assume each quarterback loses 6.7 yards per sack [1]Based on the results here., then we can calculated estimated ANY/A. And we can also calculate estimated value.

This year in college football, the average ANY/A is 6.13. Let’s use Oregon’s Marcus Mariota as an example. The Heisman frontrunner has thrown for 2,780 yards and 29 touchdowns on 277 attempts, while being sacked 23 times and throwing just two interceptions. As a result, Mariota has an ANY/A of 10.39. That’s 4.26 ANY/A above average, and over the course of Mariota’s 300 dropbacks, that means he’s provided 1,278 of Adjusted Net Yards of value over average. As it turns out, that’s the most in college football. The table below is fully sortable and searchable, and it lists the 172 quarterbacks this season with at least 50 pass attempts:

  • It’s important to remember that much more so than in the NFL, strength of schedule is a significant variable in all college football analysis. That is completely ignored here. In addition, coaching and scheme matter more, too, and that is not considered in this analysis. This is simply a quick and dirty look at the numbers.
  • Jameis Winston checks in only at #27. This is not because ANY/A is a bad way to measure quarterback play — in fact, Winston ranked 2nd in the SOS-adjusted version of this last year, while averaging 10.2 ANY/A. He’s had a down year, at least statistically.
  • Down at the very bottom of the list, in second to last place? Penn State’s Christian Hackenberg. It’s been a rough year for the Nittany Lions offense, as the offensive line is in shambles. Hackenberg, considered to be a possible first round pick in 2016, will need to put together a much better season statistically in 2015 if he wants to keep that dream alive.

The SEC West closed system is no more. If so inclined, one could note that Alabama lost to Ole Miss, and Ole Miss lost to Auburn, and Auburn lost to Georgia, and Georgia lost to both Florida and South Carolina, and Florida and South Carolina both lost to Missouri, and Missouri lost to Indiana. And Indiana is terrrrrible.

The Auburn loss to Georgia was enough to ruin this crazy streak: prior to Saturday, Auburn, Alabama, LSU, Mississippi, Mississippi State, and Texas A&M were a combined 35-0 against the rest of college football this season. But on Saturday:

  • Auburn lost badly to Georgia, 34-7. The Bulldogs are very good — and even better with Todd Gurley back — and now rank 5th in the SRS. But Georgia still did somehow lose to both Florida and South Carolina, who are a combined 9-9 this year against FBS opponents. As for the Tigers: I had been leading the Auburn bandwagon because they have easily played the toughest schedule to date in college football — oh, and Alabama is still on the schedule — but this was the straw that broke Auburn’s playoff chances.
  • LSU was shut out against Arkansas, 17-0. The Razorbacks had been 4-5, albeit with losses to Alabama, Mississippi State, Auburn, Georgia, and Texas A&M.
  • Texas A&M lost to Missouri, 34-27. The Tigers, of course, had the most embarrassing SEC performance of the season, losing to an Indiana team that is 0-6 in conference play. That’s 0-6 in the Big Ten, for you folks keeping score at home. And Missouri lost to them. As a result, any team that loses to Missouri gets to wear that shame by osmosis, and indirectly, you could stretch that all the way to Alabama.

Of course, the SRS is not based purely on wins and losses: in some ways, it isn’t based at all on wins and losses, as it is focused solely on points differential (adjusted for close games, blowouts, and home field) and strength of schedule. The table below shows the week 12 college football SRS ratings, with Alabama now moving into the top spot. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs.

The SEC West and Maximum Likelihood

The upper crust of college football

The upper crust of college football

Eight years ago, Doug Drinen wrote about the Maximum Likelihood rating system, a computer model which one could use to rank college football teams. The short, non-mathy version is this: the probability of Alabama beating Team X is equal to the rating of Alabama divided by the sum of Alabama’s rating plus the rating of Team X. You can use that formula for every game in each season, which would leave you with an enormous series of equations. From there, you would give each team a rating, and keep tinkering with the ratings until the ratings you have for each team provides the system with the maximum possible likelihood of the actual results.

To do this, you would want to give Alabama a high rating, because that would increase the likelihood of the system as a whole reflecting what’s happened on the field. In fact, you might why would we ever limit Alabama’s rating: after all, if we keep jacking up the Tide’s rating, what’s the harm? In this case, there is only one reason not to give Bama an insanely high rating: a loss in Oxford to Ole Miss on October 4th.

Speaking of the Rebels, what should their rating be? A really high one, although it needs to be capped by Mississippi’s losses to both Auburn and LSU. What about Auburn and LSU? Well, both sets of Tigers lost to Mississippi State, Auburn lost to Texas A&M, and LSU lost to both Alabama and Auburn.

You might think “okay, this seems reasonable: all these losses will help control the ratings.” But there’s a problem about to emerge. Sure, LSU and Auburn lost to MSU, but the Bulldogs are undefeated, so there’s no reason not to give Mississippi State a rating of a zillion. And we already know that Alabama is going to get a high rating, so LSU’s loss to the Tide won’t hurt much. LSU lost to Auburn, but isn’t Auburn’s rating really high? The Tigers don’t get dinged for losing to MSU, while the Texas A&M loss doesn’t hurt because A&M’s only losses are to Alabama, Mississippi, and MSU. [continue reading…]

The Tide escaped Baton Rouge with a win and its playoff goals in sight

The Tide escaped Baton Rouge with a win and its playoff goals in sight.

The playoff picture is beginning to emerge. With most teams having just three games left in the college football regular season, we get a sense of the task ahead for the college football playoff committee. And, unfortunately, it feels as though the committee is going to use some variation of the following logic:

Step 1: Rank teams in ascending order by losses

Step 2: Rank teams by some combination of eye test and recency of last loss

There are still three undefeated teams: Mississippi State, Florida State, and Marshall. MSU and FSU seem likely to take the top 2 spots, and there does not appear to be much thought given to the process other than that. Marshall is not in the conversation, and for good reason: they have a bottom three strength of schedule according to the SRS (you can sort by SOS in the table below).

Mississippi State still ranks just 7th in the SRS, but remember, that’s a predictive ranking. I would put the Bulldogs atop my mythical rankings for playoff purposes, too. But Florida State? FSU has three notable wins on its resume, and none of them were in convincing fashion. Those wins came against Clemson (#25), Notre Dame (#31), and Louisville (#32), and one would think that the 2nd best team in the country would defeat those teams more convincingly. Regardless, as defending champions and riding a 25-game winning streak, nobody will argue against the Seminoles.

But the next two spots? That’s where the debate begins. Ignoring 9-1 Colorado State (very soft strength of schedule), 8-1 Duke (same), and 8-1 Nebraska (only one win — against SRS #23 Miami — against an SRS top-65 team), there are 6 teams with one loss that seem likely to take the #3 through #8 spots in the next edition of the playoff rankings. A best guess as to where those teams land on Tuesday:

  • #3 Oregon – the Ducks ranked 4th last week, and won in convincing fashion at Utah in week 11, while #3 Auburn slipped at home against Texas A&M.
  • #4 Alabama – a chance the Tide move ahead of Oregon because of a “big win” against a high-profile opponent in LSU. Will the committee penalize Alabama for needing overtime to beat LSU, or praise Alabama because by virtue of the game going to overtime it means LSU is a really good team (This, of course, is known as SEC country logic)?
  • #5 TCU – the Horned Frogs were 6th last week, and handled Kansas State, which ranked 7th in the rankings last week. Could TCU jump Alabama or Oregon? After all, #6 beating #7 should count more than beating #16 (LSU in last week’s rankings) or #17 (Utah), but don’t hold your breath for a team like TCU getting a wave of momentum. In fact, we might even see the Horned Frogs drop, because…
  • #6 Baylor – the Bears demolished Oklahoma in Norman in week 11. And Baylor defeated TCU back in week seven. The committee is supposed to value head-to-head, but does that mean Baylor should be ranked ahead of TCU? That argument would hold more weight, at least to me, if Baylor hadn’t lost by 14 points to West Virginia, a team that TCU happened to beat. If West Virginia had just one conference loss, Baylor, TCU, and West Virginia would all be tied and be 1-1 in the three-team round robin; instead, crediting Baylor for West Virginia losing other conference games somehow makes that Baylor loss… better? I don’t follow that logic, but who knows what the committee will do. Frankly, choosing between the top two Big 12 teams is an exercise in hair splitting. Will the recency of Baylor’s loss be held against the Bears vis-a-vis TCU? That sounds silly, but Baylor dropped below TCU after losing to West Virginia, and perhaps the Bears will never rise above them again.
  • #7 Arizona State – the Sun Devils crushed Notre Dame, and were ranked ahead of Baylor last week. Perhaps ASU will remain in the 6 spot, but frankly, the committee can punt on this question. If Arizona State and Oregon both win out, the Pac-12 championship game will turn into a de facto play-in game for the college football playoffs. Arizona State lost by 25 points to UCLA — will that weigh on the committee’s mind in choosing among the 1-loss teams? ASU’s best wins are against USC, Utah, Notre Dame, and Stanford, which still leaves a bit to be desired.
  • #8 Ohio State – just a guess, but the assumption here is the committee puts OSU in the 8 slot this week. Ohio State convincingly defeated Michigan State this week, easily the most impressive performance by the Buckeyes this year. But a home loss to Virginia Tech looks terrible in retrospect, and OSU’s second best win was against… Maryland? Penn State? Cincinnati? If Ohio State is ranked in the top 8 this week, it’s a sign that the committee is basically operating on 4th grade level. First, rank the team by losses, then….

When we go to the 2-loss teams, Auburn and Ole Miss stand out. The Tigers in particular deserve to be ahead of both Ohio State and Arizona State, in my opinion, and Auburn’s resume would only get stronger with road wins against Georgia and Alabama. Auburn has defeated Ole Miss, LSU, and Kansas State, wit two of those games coming on the road. If going 3-2 in five games that are @Ole Miss, vs. LSU, @KSU, @Mississippi State, and vs. Texas A&M supposed to be less impressive than going 4-1 @Michigan State, vs. Virginia Tech, @Maryland, @Penn State, and vs. Cincinnati? I am not buying that logic at all, and that still ignores Auburn’s wins against Arkansas, Louisiana Tech, and South Carolina, teams that all rate as tougher than Penn State and Cincinnati.

As for Ole Miss, the Rebels went 3-2 vs. Alabama, @Auburn, @LSU, vs. Texas A&M, and vs. Tennessee. Is it clear that such a record is worse than going 4-1 vs. UCLA, @Southern Cal, vs. Utah, vs. Notre Dame, and vs. Stanford? And Ole Miss still has a chance to pad its resume with a win on the road against Mississippi State.

If the committee is using strength of schedule solely as a tiebreaker after sorting teams by losses, [1]You know, after eliminating Marshall, Colorado State, Duke, and Nebraska for strength of schedule., then shame on the committee. The table below shows the week 11 college football SRS ratings, with Alabama now moving into the top spot. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs.

Heartbreaking

Heartbreaking.

From one perspective, Saturday brought one of the cruelest moments in years. In a must-win game for Ole Miss, the Rebels played a back-and-forth contest with perhaps the best team in college football. Trailing 35-31, Bo Wallace and the offense took over on the Mississippi 48-yard line with just over three minutes remaining. The Rebels moved quickly down the field, and on short pass to Laquon Treadwell appeared to turn into the go-ahead score. Just as Treadwell crossed the goal line, he was tackled from behind, suffering an injury that you knew was bad as soon as it happened. As it turned out, Treadwell broke his leg, and then the insult came. Upon review of the score, while Treadwell crossed the goal line, the ball did not, and he fumbled as he was taken down. Auburn recovered in the end zone, and the Tigers would prevail. [continue reading…]

In many ways, week 9 was an uneventful week of college football. Of the top 18 teams in last week’s SRS, only one lost in week 9. On the surface, the loss by Ole Miss — ranked 2nd in the SRS last week and 3rd in the polls — was a big loss. But as long as the Rebels keep winning, it wasn’t a big deal at all. Ole Miss, like Mississippi State, like Alabama, like Georgia, and like Auburn (more on them later) all control their own destiny for the playoffs. Ole Miss still has to play Auburn, Arkansas, and MSU, so it’s not as though things will be easy for the Rebels; but they do control their own destiny, just as they did a week ago.

Among top-30 SRS teams last week, only three others lost, and in two of those games it was to fellow top-30 teams. Utah (#22 in last week’s SRS) defeated Southern Cal (#19) on a touchdown pass with 8 seconds left, to give the Utes a 24-21 home win. Tennessee (#24 last week) lost at home to Alabama in the Lane Kiffin Bowl. The one real surprise was Virginia Tech (#29) losing 30-6 at home to a Miami team that was just 43rd in the SRS entering week 9.

The table below shows the SRS ratings through nine weeks. Breaking up the SEC West stranglehold at the top is TCU, and the Horned Frogs now lead the nation in scoring. It appears as though style points may not be an issue, so for TCU, the biggest hurdle may just be finishing the year 11-1. For the Horned Frogs, the toughest two games remaining are the next two: at West Virginia next week, and against Kansas State a week later. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs. Some more playoff thoughts about the jump: [continue reading…]

Every week, I publish my college football Simple Rating System scores for each of the 128 FBS teams. But to run the calculation — using this methodology — I also have to derive ratings for each non-FBS school, too.

Below are the SRS Ratings for all non-FBS college football teams through nine weeks. [continue reading…]

Last week, three Big 12 teams occupied the 4-5-6 spots in the rankings, making the Big 12 look like an obvious contender to take one of the four spots in college football’s first ever playoff. Then week 7 happened.

Yesterday, West Virginia won at home against Baylor, 41-27, while Oklahoma lost in Manhattan to Kansas State, 31-30. [1]The Sooners not only missed an extra point, but a 19-yard field goal in the game’s final minutes. TCU blew out Oklahoma State, 42-9, which only increases the pain associated with how the Horned Frogs blew the Baylor game a week ago. When SEC teams beat up each other, it shows the strength of the conference. When every other conference beats up each other, it shows how the conference isn’t as good as we thought. That’s an extreme version of the narrative, but that does seem to be the thought process for many in the media. After week 7, the Big 12’s big three is now a big four with Kansas State [2]Why not West Virginia? Sure, the Mountaineers are 5-2 with only losses to Alabama and Oklahoma, but the SRS so far thinks WVA belongs in a lower tier than the top teams in the conference. joining the mix. All four are in the top 12, but none are in the top 4. More importantly, TCU, the top Big 12 team, ends the season with Kansas, Texas, and Iowa State. It’s going to be tough for TCU to gain a lot of momentum in December with that finish to the schedule, and will TCU look that much different than say, the winner of the Oklahoma/Baylor game? Kansas State could wind up undefeated in the conference, but what will that say about the Big 12 relative to the SEC if KSU’s only loss was to Auburn?

It’s definitely too early to really think through possible scenarios, but that doesn’t make it any less fun. Below are the week 8 ratings. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs. Some more playoff thoughts about the jump: [continue reading…]

The Bulldogs pushed aside the Tigers in week 7; just not in the SRS

MSU pushed aside Auburn in week 7; (but not in the SRS).

In last week’s rankings, Auburn stood head and shoulders above the rest of college football. As a result, even a 15-point loss on the road against Mississippi State wasn’t enough to nudge the Tigers from the top spot. Is this a problem? Not really. The SRS ratings are predictive; they are not designed to tell you which teams are the most deserving or which schools have accomplished the most. Instead, they are intended to give you an idea of what might happen in a future game between any two teams.

Auburn’s rating is amplified by a 41-7 victory against LSU, which stands out as the most dominant performance of the year. The Tigers also crushed Arkansas by 24, a margin that looks more impressive every week. Other than yesterday’s loss, Auburn’s “worst” performance of the year by SRS standards was a 6-point win on the road against Kansas State (#14 in the SRS), which would be the best game of the year for all but a handful of teams.

The Mississippi schools check in at #2 and #3 in the SRS this week; Alabama and Texas A&M are #8 and #9, giving the SEC West five teams in the top ten yet again. Auburn, with the double-edged sword of a brutal schedule, will have no problem getting back into the playoff discussion if the Tigers can win out. Georgia, fresh off a 34-0 thumping of Missouri, is now 7th in the SRS. But I want to focus on schools 4, 5, and 6 in the ratings. All are from the Big 12, a conference doesn’t appear to be getting much respect nationally.

The ten-team conference plays a round robin schedule, meaning each team gets nine division games. That leaves only 3 nonconference games for each school, and the class of the conference — Baylor, Oklahoma, and TCU — are already done with that part of their schedule. It makes sense to analyze these teams as a group, because for SRS purposes (and based on the two head-to-head games), these three teams are all about equal. In their nine nonconference games, they went 9-0 with an average margin of victory of 41 points, and all wins came by at least 23. Of course, that schedule was loaded with cupcakes: other than Tennessee (currently 12th in the SRS), the only semi-respectable opponents were Minnesota (#38) and Louisiana Tech (#50). And the Vols game is certainly helping: Tennessee is 3-3, but the losses were by 1 point to Florida, 4 to Georgia, and 24 to Oklahoma. [continue reading…]

Thoughts on SEC West schedules

The SEC West is the best division in all of college football. The division is 31-6 this year, with all six losses coming at the hands of other SEC West teams. There have been only three inter-divisional games in the SEC this year, and the West teams came away with three blowout victories: Alabama over Florida (42-21), Texas A&M over South Carolina (52-28), and Ole Miss over Vanderbilt (41-3). In Power 5 play, Arkansas, Alabama, and Auburn have notched wins over Texas Tech, West Virginia, and Kansas State, while LSU knocked off Wisconsin. And Ole Miss defeated Boise State and Memphis, too.

Auburn, Mississippi, MSU, Alabama, and A&M all are in the top 10 of the SRS, and LSU and Arkansas are in the top 20. So what happens if these teams beat up on each other? Each school plays each of the other six SEC West teams. While there’s a good chance at least one of these schools goes 5-1 or 6-0 in division play, there’s also a chance we end up with a multi-team tie atop the division at 4-2. The actual tiebreakers are the typical boring type that you can imagine, but we need not restrict ourselves to the creativity capacity of executives of the Southeastern Conference. So today, I’m ranking schedules. Since this is not the tiebreaker that the SEC would actually use, you can think of this as how-to guide to rooting for people who have morals: [continue reading…]

Ole Miss pulled off the big upset

Ole Miss pulled off the big upset.

Early in the day, Mississippi State blew out Texas A&M in Starkville, 48-31. That was the first half in the most incredible football day in Magnolia State history. What happened next was much more dramatic.

Ole Miss had lost 10 straight games to Alabama, with 9 of those games coming by at least 22 points. The last three years, the Crimson Tide had won by an average of 36.7 points. Last year, a 3-0 Ole Miss team — fresh off of a blowout win in Texas — lost in Tuscaloosa, 25-0. So while the Rebels entered Saturday with a 4-0 record and a top-15 ranking, it would be fair to wonder how they would handle an Alabama team that was still Alabama.

Early on, the Tide looked like the better team. Amari Cooper was not dominating, but T.J. Yeldon looked great, en route to a 100-yard day. Quarterback Blake Sims looked smart and efficient, while Ole Miss couldn’t seem to get much going on offense like just about every opponent ever against Alabama. Still, the Rebels defense had played well enough to keep the Tide to just seven first half points, and the game looked to be 7-3 at the end of the half. That is, until what appeared to be the turning point of the game.

In the final seconds of the half, a screen pass to I’Tavius Mathers looked to be uneventful, until Cyrus Jones pulled off the trifecta — strip, fumble recovery, return for a touchdown. Replays showed that Jones committed a blatant facemask penalty, which likely lead to the fumble, but the refs didn’t see it. So after a great first half, a bad call meant Ole Miss was suddenly down 14-3. This seemed like a recipe for yet another Alabama win over the Upstart Of the Week.

But the weirdest thing happened in the second half. Ole Miss didn’t just outscore Alabama, it outplayed them. And not by an insignificant margin. Bo Wallace, Laquon Treadwell, and Evan Engram (other than a huge drop) were dominant in the second half, while the Ole Miss defense continued its excellent play. A gorgeous touchdown to Jaylen Walton gave Ole Miss a touchdown lead, but in typical Ole Miss fashion, the team botched the extra point not once, but twice. [1]First, the kick clanked off the upright. A roughing the kicker penalty gave the Rebels another chance, but the second extra point attempt was blocked.

With Ole Miss now clinging to only a 6-point lead, you could hardly blame anyone for expecting Alabama to win the game with a last second touchdown. A 30-yard catch and run by Cooper on the final drive put the Tide in inside the Ole Miss 30. But an incredible interception by Senquez Golson sealed the victory, and the day was complete: Mississippi not only beat, but outplayed Alabama, in a crucial game in a battle for SEC West supremacy. The game (and the aftermath) was everything that was great about college football.

Which almost makes it seem silly to transition to college football ratings, since we are still too early in the year for these ratings to hold significant meaning. Last week, I unveiled the initial SRS ratings. In perhaps two weeks, the ratings will start to really hold up, but for now, these are mostly a gut check. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs. As a reminder, these ratings are intended to be predictive only, and not intended as a way to rank college football teams for any other purpose.

Your Guide to Rooting Against the SEC

I got an email a few days ago with an idea for a post. Because coming up with one entire idea every day can get to be a grind after awhile, sending me such an email is Step Two to getting on my good side (Step One, of course, is submitting a guest post). I can use all the help I can get. Here was the email in full.

Vanderbilt lost to freakin’ Temple this year. While it would be great if Vanderbilt went undefeated in SEC play, that’s not going to happen. So what else can an SEC-hater root for this year that would make the SEC look bad?

If you’re rooting against the SEC as a whole — and getting involved in conference wars is a surefire way to get lost down the rabbit hole — what teams do you want to keep an eye on this year?

  • As our emailer suggested, having Vanderbilt fare well in SEC play would be one way the conference as a whole would look worse. As it stands, that’s exceedingly unlikely to happen. Vanderbilt’s best game of the year was a 10-point loss to Kentucky; the Commodores look to be the worst team in the conference, which will minimize the impact of the Temple loss.
  • SEC teams have not lost any other games against non-Power 5 conferences. So what’s next? In fact, the conference has lost just two other out-of-conference games.
  • Tennessee lost to Oklahoma 34-10, but the Sooners are the top team in the early edition of the SRS rankings. The Vols may be pretty good this year — they nearly beat Georgia last weekend — but it’s going to be hard for this loss to wind up reflecting badly on the SEC as a whole. Absent an unexpected SEC East division title, the biggest hope here would be for the Vols to be competitive with Alabama. In that case, if the Sooners and Crimson Tide are both battling for one playoff spot, that data point could be used against ‘Bama.
  • But by far the biggest blemish came when Indiana — Indiana(!) — won in Missouri, 31-27. The Hoosiers are one of the worst teams in a not very good Big Ten. In the team’s other three games, Indiana beat an FCS school, lost badly at home to Maryland, and lost to a MAC school (Bowling Green). Every game Mizzou wins could theoretically devalue the conference (or at least the SEC East) as a whole. After the Tigers beat South Carolina last weekend, Missouri is off to a good start in the team’s bid to repeat as SEC East champs. Assuming Indiana tanks, this is the one data point SEC haters can cling to so far.

The past couple of weeks, I was using a quasi-Elo style rating system to produce college football team ratings. And while after five weeks it is still far too early to put much faith in any computer ratings, we can at least begin framing the discussion of which are the most impressive teams in college football. So, as we did last year, the first edition of the college football SRS ratings are coming out at the end of September. As a reminder, here is the methodology:

1) For each game not played at a neutral site, 3 points are given to the road team. After that adjustment, all wins and losses of between 7 and 24 points are recorded exactly as such. This means that a 24-10 road win goes down as +17 for the road team, -17 for the home team.

2) With one exception, wins of 7 or fewer points are scored as 7-point wins and losses of 7 or fewer points are scored as 7 point losses. So a 4-point home win goes down as +7 (and not a 1) and a 1-point home loss is a -7 (and not a -4). The one exception is that road losses of 3 or fewer (and home wins of 3 or fewer) are graded as ties. So a 21-20 home victory goes down as a 0 for both teams.

3) Wins/Losses of more than 24 points are scored as the average between the actual number and 24. This is to avoid giving undue credit to teams that run up the score. So a 75-point home win goes down as a 48-point win.

Once we have a rating for each team in each game, we then adjust each result for strength of schedule. This is an iterative process, where we adjust the ratings hundreds of times (to adjust for SOS, you have to adjust for the SOS of each opponent, and the SOS of each opponent’s opponent, and so on.) in Excel. Then we produce final ratings, where the SRS rating is the sum of the Margin of Victory and Strength of Schedule in every week.

After five weeks, what are the results? As usual, the table is fully searchable (type “-0″, for example, to see a list of undefeated teams, or SEC to see all SEC teams.) Right now, the number one team is Oklahoma, with an average (adjusted) Margin of Victory of 24.6 points per game against an average opponent that is 43.3 points better than average (average includes all football teams at all levels, so all FBS teams will have a positive grade). Among undefeated teams, the only teams with tougher to-date schedules than Oklahoma are Auburn and UCLA. Below shows the ratings for all 128 FBS teams.

Week Four College Football Ratings (2014)

Last week, I unveiled some ELO-style college football ratings. Next week, with five weeks of data, I plan to run the first edition of the traditional SRS ratings. But for one more week, let’s stick with the current format.

Step 1) Twenty-five FBS teams were off in week 3, leaving 103 teams to analyze.

Step 2) In 25 of those matchups, one team had an SRS rating at least 15 points higher than its opponent. In 22 of those games, the favorite one; as a result, there is no change in either team’s rating following that game, so Oregon does not get downgraded for only beating Washington by 7 points on the road. But the three “upsets” include the big surprise of the week: Indiana going into Columbia and upsetting Missouri, 31-27. For those games, we’ll include them in Step 4.

Step 3) After eliminating the 22 heavy favorites who were victorious, there are 81 teams remaining. While some of those games were against FCS schools, 16 of the heavy underdogs in those games were against FBS schools. Since those teams will not have their ratings change, that leaves 65 teams to analyze.

Step 4) For all other teams, I modified each team’s rating following the result of that game, with 85% of the new rating coming from the old rating, and 15% coming from that single game.

Below are the ratings through four weeks. As always thanks to Dr. Peter R. Wolfe for providing the weekly game logs. [continue reading…]

Week Three College Football Ratings (2014)

Mariota and the Ducks look as good as any team in the country

Mariota and the Ducks look as good as any team in the country.

Regular readers know that I publish weekly college football ratings using the Simple Rating System. The catch is that the SRS isn’t a viable option in the first few weeks of the season; until we have more interaction among the top teams, we can’t really generate computer ratings.  Frankly, running an SRS program today would be pretty useless.

Consider that a team like Arizona State has played Weber State, New Mexico, and Colorado. Auburn has played Arkansas (the Razorbacks are not very good) and San Jose State. Oklahoma has played Louisiana Tech, Tulsa, and Tennessee (the Vols are not very good). So what can we do?

One thing we could do is to use the concept of Elo Ratings. But calculating Elo ratings in this context is no simple task, and there’s a good chance my buddy Neil is going to do that, anyway, so I thought I would try simpler process. I’ll give a high-level overview of the process here, then present the rankings, and then provide all the nuts and bolts for those interested at the bottom of the post. [continue reading…]

FSU is a heavy favorite to wind up in the national title game again

FSU is a heavy favorite to wind up in the national title game again.

The Simple Rating System is a set of computer rankings that is focused on only two variables: strength of schedule and margin of victory. I publish weekly college football SRS ratings each season, and you can read more about the SRS there. Last year, I took the Las Vegas point spreads for over 200 college football games to come up with a set of power rankings. By taking every data point, and using Excel to iterate the ratings hundreds of times, I was able to generate a set of implied team ratings.

Well on Friday, the Golden Nugget released the point spreads for 200 games (h/t to RJ Bell). You might not think we can do much with just a couple hundred games, but by using an SRS-style process, those point spreads can help us determine the implied ratings that Las Vegas has assigned to each team.

We don’t have a full slate of games, but we do have at least 1 game for 77 different teams. Theoretically, this is different than using actual game results: one game can be enough to come up with Vegas’ implied rating for the team. Purdue may only have a spread for one game, but that’s enough. Why? Because Purdue is a 21-point underdog at a neutral field (Lucas Oil) against Notre Dame, and we have point spreads for the Fighting Irish in ten other games. Since we can be reasonably confident in Notre Dame’s rating, that makes us able to be pretty confident about Purdue’s rating, too.

The system is pretty simple: I took the point spread for each game and turned it into a marvin of victory, after assigning 3 points to the road team in each game. For example, Alabama is a 6-point home favorite against Auburn. So for that game, we assume Vegas believes the Tide are three points better than the Tigers; if we do this for each of the other 199 games, and then iterate the results hundreds of times, we can come up with a set of power ratings.

College Observations from the 2014 Draft

Messing with Texas

By now, you’ve probably heard that no player from the University of Texas was drafted. Jackson Jeffcoat was the Big 12 co-Defensive Player of the Year, but that honor wasn’t enough to enable him to hear his named called on any of the three draft days. [1]as Bill Barnwell points out, Jeffcoat’s tumble provided a good counter to those arguing that Michael Sam was going to go undrafted despite being the SEC co-Defensive Player of the Year solely … Continue reading The draft was first instituted in 1936, and not since 1937 had an NFL draft has been Longhorn-free.  From 2000 to 2013, players selected from the University of Texas were, in the aggregate, responsible for about 37 points of value per season using the values from my pick value chart.  That’s the 10th most of any school during that period, behind only Miami (FL) (51), Southern Cal (49), Florida State (42), LSU (39), Ohio State (39), Georgia (39), Alabama (38), and Florida (38). But UT wasn’t the only school that had a rough weekend:

  • Illinois, which ranked 37th in draft value from 2000 to 2013 (14 points), was the next highest-ranked school after Texas to get shut out of the 2014 draft.  Hawaii (53rd), Rutgers (59th), and Cincinnati (66th) were other top-70 programs from ’00 to ’13 that did not have a player selected this year. A couple of other schools from power conferences — Northwestern and Kansas — were also left out in the cold.
  • For Texas and Illinois, injury was added to insult. No only were no Longhorns drafted, but three Aggies — Jake Matthews, Mike Evans, and Johnny Manziel – went in the first round, while TCU had a first round pick (Jason Verrett), Texas Tech had a second round pick (Jace Amaro) and Baylor had five players drafted.  No Illini went in the draft, but Northern Illinois had two players (including 1st round safety Jimmie Ward), Eastern Illinois had a second round pick (Jimmy Garoppolo) and even Illinois State had a player selected (Shelby Harris in the 7th round).
  • It was also a rough draft for a few other schools. Miami normally dominates the draft, but only three Hurricanes were selected: two offensive lineman and a punter.  Brandon Linder was drafted 93rd overall to Jacksonville, followed by Pat O’Donnell to Chicago at 191 and Seantrel Henderson to the Bills at 237.
  • The Georgia Bulldogs had just two players drafted, both in the fifth round: quarterback Aaron Murray and tight end Arthur Lynch.
  • Sooners fans probably want to gloat over Texas, but this was a pretty ugly year for Oklahoma, too.  The school’s highest-drafted player was Jalen Saunders at 104. That marks the first time since 1997 that no Sooner was drafted in the top 100 picks.

Small Schools Making Draft History

There were four players who came from schools that haven’t had a single player drafted in the last 20 years.

  • At pick 198, New England took defensive end Zach Moore out of Concordia University in St. Paul, Minnesota. He’s not only the first player ever drafted from the school, but no player from the Division 2 program has ever made it to the NFL. Last year, Concordia only ranked as the 26th best football team in Division 2 through 13 weeks (by reference, Pittsburgh State ranked 8th).
  • Finally, Terrence Fede out of Marist was drafted by the Dolphins with the 234th pick. Fede, like Desir and Moore, made history by becoming the first player ever drafted out of his school. Marist, located in New York state, plays in the Pioneer Football League, but ranked as just the 70th best FCS school last year.

The Crimson Tide Reign is Over

For three straight years, more draft capital was spent on Alabama players than those from any other school. The reign is over, as Alabama tumbled all the way down to … fourth place. Texas A&M led the way: while only three Aggies were selected, they were drafted high enough to make College Station the most valuable town for the 2014 draft with 60.3 points of value. Next up was LSU (57.0), which also led the way with 9 players drafted (but only one in the top 50). In third place was Notre Dame (54.7 points, 8 players drafted, three in the top 75), followed by Alabama (54.3, 8 players), Florida State (54.2, 7 players), Auburn (52.4, 4), Louisville (49.9, 4), and Ohio State (49.8, 6).

Texas A&M, Louisville, and Notre Dame had excellent drafts especially by their standards: none of the three ranked in the top 20 from ’00 to ’13 in draft value provided (the Fighting Irish were 21st, the Aggies were 24th, and the Cardinals were down at #50).  Other schools that had comparably big years: UCLA, Auburn, Buffalo, Central Florida, South Carolina, and Clemson. Okay, in the case of UCF it was just because of Blake Bortles (running back Storm Johnson, at pick 222, was the only other Knight drafted) and for Buffalo it was Khalil Mack and done. But still, neither program had ever had a player drafted in the top ten before, so a top-five pick is a pretty remarkable accomplishment.

1 as Bill Barnwell points out, Jeffcoat’s tumble provided a good counter to those arguing that Michael Sam was going to go undrafted despite being the SEC co-Defensive Player of the Year solely because he was openly gay.  As it turns out, being co-DPOY isn’t worth as much as you might think.  Jeffcoat landed with the Seahawks, though, so he and Sam will both get a chance to prove their mettle in the NFL’s toughest division.

Which College Conferences Dominate the NFL Draft?

On Sunday, I used my draft value chart to determine how NFL teams valued various positions. Today, I’ll use the same method to see which schools and conferences dominate the NFL Draft. You are not going to be surprised to discover that USC Trojans have dominated the draft over the last ten years. You’ll be even less surprised to see that SEC teams have accumulated the most draft value, and the most value per team, of any conference. But let’s put some numbers on what we all know. Here’s what I did:

1) Using these draft values, assign a value to every pick in every draft from 2004 to 2013.

2) Calculate the amount of draft capital assigned to each college team by summing the values from each draft pick for each player from that college.

3) Sum the values for each school in each conference. Note: I am using the school-conference affiliations as of the 2013 season, so the SEC gets credit for the last ten years of Texas A&M, and the ACC gets a decade worth of Pitt draft picks. (Speaking of Pitt, regular readers may recall last year’s two posts on college and NFL team connections). On the other hand, Maryland and Rutgers are not credited to the Big Ten… yet. This is almost certainly not the ideal way to handle the situation, but any other approach would be too time consuming and as a reminder, nothing about college football makes any sense, anyway.

Based on that methodology, the table below shows the 100 schools that have produced the most draft value from 2004 to 2013. By default, I’m listing only the top 10, but you can change that in the dropdown box to the left: [continue reading…]

Sometimes, it’s hard to believe that it’s 2014. With draft season now in full gear, I wanted to take a few minutes and look at the stats of the top college quarterbacks from last year. Unfortunately, that’s easier said than done. I couldn’t find a site that presented a full list of all college quarterback stats, including sacks, which is, of course, insane.

College football records sacks as rushing plays for the offense; as a result, knowing how many sacks Johnny Manziel or Teddy Bridgewater took last year is not that easy to find. So here’s what I did:

1) Using team game log data, I found the number of sacks for each defense in each game.

2) Next, I recorded the percentage of team pass attempts recorded by each quarterback for his offense in each game (usually close to 100%).

3) I synched up these two sets of data, and multiplied each quarterback’s percentage of team pass attempts by the number of sacks by his opponent’s defense in that game.

That provided me with some useful estimated sack data. From there, I calculated each quarterback’s Adjusted Net Yards per Attempt average, which is simply (Gross_passing_yards + 20*PassTDs – 45*INTs – Estimated_sack_yards_lost) / (Pass_attempts + Estimated_sacks). I did this for the 140 quarterbacks with the most pass attempts in the FBS (sorry, Jimmy Garoppolo fans) in 2013.

Since the number of pass attempts vary wildly at the college level, I also calculated a Value Over Average statistic. The 140 quarterbacks had an average ANY/A of 6.44, so the Value metric (which is what the table is sorted by) is simply (ANY/A – 6.44) * (Pass_attempts + Estimated_sacks). Here’s how to read Bridegwater’s line, the Louisville quarterback who many believe will be the first quarterback selected in the draft.

Bridgewater provided the 5th most passing value by this formula, completing 303 of 427 passes for 3,970 yards with 31 touchdowns and 4 interceptions. He took 25.5 sacks and lost 185 yards, and had a sack rate of 6% (if I included the percent sign, the table would not sort correctly). Bridgewater also averaged 13.1 yards per completion and had a 9.34 ANY/A average, which combined with his number of dropbacks, means he added 1,310 adjusted net yards of value over average. By default, the table below only shows the top 25, but you can sort and/or search to find each of the 140 quarterbacks (and you can change the number of quarterbacks displayed via the dropdown box to the left).
