Consecutive Playoff Losses For a Franchise

From 1993 to 2015, the New York Islanders lost eight consecutive playoff series, beginning with a loss in the conference finals to Montreal in 1993, and culminating in a heartbreaking, 7-game series loss last year to Washington. Last night, the Isles came from behind and defeated Florida, to win the series, four games to two.

So the streak stopped at eight for the Islanders; as it turns out, the longest streaks for consecutive playoff losses in NFL history is also at eight, with two of those streaks being active. [click to continue…]

Yesterday, I wrote how the NBA seemed to undervalue the three-point shot for many years. While the 3-point shot was consistently the better EV play, and the ratio of three-point shots to overall shots was increasing, it didn’t seem to increase quickly enough. As pointed out in the comments, one could make a pretty similar claim about pass/run ratio in the NFL.

It’s a little misleading to start things in 1970, since that’s really the beginning of the dead air era in football history. Pass efficiency was very high in the late ’40s and parts of the ’60s, so a chart beginning in 1970 would inaccurately imply a linear progression of the passing game. That said, because first down data is spotty the farther back we go, and because of the complexity involved in deciding how to treat the AFL, I’m going to limit myself today to the period from 1970 to 2016.

Yesterday, I looked at the Pythagenpat records for all teams since 2000. Since I crunched all that data, I thought it would be fun to look at the biggest outlier teams.

The 2003 Steelers were not very good. Pittsburgh went 6-10, scoring 200 points and allowing 327 points. Because of regression to the mean, the ’04 Steelers were expected to be a little better, and finish with 7.2 wins. Instead, behind a rookie Ben Roethlisberger and an outstanding running game and defense, the Steelers went 15-1, exceeding expectations by 7.8 wins.

Last year’s Panthers also went 15-1, and have a similar story. Cam Newton, the AP MVP, was more of the driving force, of course, but a great running game and defense powered the team. But based on a mediocre ’14 season, Carolina was expected to win only 7.8 games, so the 2015 Panthers exceeded expectations by 7.2 wins.

The third biggest outlier? That would be the ’07 Patriots, who went 16-0 with a projection of just 9.5 wins. The next year, New England was projected to win 10.99 games, and… went 11-5.

The table below shows each team since 2000, and their number of projected and actual wins. The table is sorted by the difference column: [click to continue…]

The Browns have been running in place

The Browns have been running in place

A good read from ESPN yesterday about new Clevleand Chief Strategy Officer Paul DePodesta, who is being labeled as the man who will (attempt to) bring Moneyball philosophies to the NFL. Putting aside the inaccuracy of that statement — Moneyball philosophies mean different things to just about everyone, and such philosophies are already a staple in many organizations — there will be a certain spotlight cast on DePodesta in Cleveland. And, according to some statistical analysts, that’s a bad thing.

At MIT Sloan Sports Analytics Conference in March, unilateral fear existed inside analytics community that systemic ineptitude of Browns franchise will be too substantial for even DePodesta to repair. Failure would damage legacy of beloved industry pioneer and set field of sports data science back decades. “If you love analytics and want it to grow and succeed in the NFL, then you know Cleveland is a nightmare scenario,” states NFL executive with 20 years of experience in analytics. “Cleveland is a crazy, terrible place for this to be tested in football.”

The idea that Cleveland is too toxic to be resurrected is…. well, it’s more supported by the data than you might think. Certainly DePodesta could turn things around, but if he doesn’t, he’ll just be the next man in a long line of failed Browns executives. You won’t be surprised to learn that Cleveland has the worst winning percentage in the NFL since re-entering the league in 1999. But even accounting for the fact that the Browns have been bad, Cleveland has still underperformed to the tune of about 26 wins over the last 16 years, most in the NFL.

How did I arrive at that number?

  • First, I calculated each team’s Pythagnpat winning percentage in each season beginning in the year 1999, which is based solely on the number of points scored and allowed by each team. For example, in 2014, the Browns scored 299 points and allowed 337, which translates to a 0.429 Pythagenpat winning percentage (the Browns actually beat that slightly, by going 7-9).
  • Next, I ran a regression on the years 1999 to 2014, using Year N Pythagenpart winning percentage to predict Year N+1 wins. This would, in theory, help out the Browns, because Cleveland would be expected to win fewer games than the average team in Year N+1 because the Browns typically have a poor Year N performance. The best-fit formula was 0.311 + 0.376 * Yr_N_Pyth_Win%. This shows that regression to the mean is a large factor, because past performance only accounts for 38% of what goes into a team’s projection for Year N+1; the remainder is a constant for all teams.

Using Cleveland’s 2014 line as an example, the 2015 Browns would have been expected to win 7.6 games, because the 2014 team had 6.9 Pythagenpat wins, and regression to the mean drives that number towards 8 wins. But Cleveland won just 3 games last year, falling 4.6 wins shy of expectation. And that’s only the second-most disappointing season of the new Browns era: in ’08, Cleveland fell 4.7 wins shy of its Pythagenpat prediction. Take a look at every Cleveland season from 2000 to 2015 (obviously there was no prediction for ’99, since there was no ’98 team): [click to continue…]

Yesterday, I measured the age of each team’s passing attack by calculating the yards-weighted age of each player who gained either a passing or receiving yard. Today, the historical results.

I’ve written a bit about Terry Bradshaw and his terrible rookie season of 1970, mostly in the context of number one picks taking a long time to break out. But here’s something that often gets lost in the mix: Bradshaw was just one of many inexperienced players on the ‘70 Steelers.

Bradshaw played as a rookie that year at age 22 (Terry Hanratty also started 6 games, and was also 22). The top 6 players in receiving yards on the ’70 Steelers were wide receiver Ron Shanklin (age 22), wide receiver Dave Smith (23), tight end Dennis Hughes (22), fullback John Fuqua (24), wide receiver Hubie Bryant (22), and wide receiver Jon Staggers (22). Incredibly, five of those six players were rookies, with Frenchy Fuqua being the sole exception — and he was drafted in 1969! In the ’70 draft, Pittsburgh took Bradshaw with the 1st overall pick, drafted Shanklin at 28, Staggers in the 5th round, and Smith in the 8th round, while both Hughes and Bryant were undrafted free agents that year. That’s unbelievable, and makes the ’70s Steelers passing attack akin to an expansion team — or rather, an expansion team with almost no access to the veteran market. As a result, Pittsburgh’s 1970 passing attack ranks as the youngest in history: [click to continue…]

Bortles led the 2nd youngest passing offense in the NFL

Bortles led the 2nd youngest passing offense in the NFL

After a 1-4 start to the season, it might have felt like an odd time to write about how the Jacksonville Jaguars could have the next great offense. But in many ways, Jacksonville’s passing attack only got better as the season went along. Some (the majority?) of the big numbers were more of a function of quantity than quality, but the numbers really were big. Consider:

  • Blake Bortles finished tied for 2nd in passing touchdowns and 7th in passing yards
  • Allen Robinson finished tied for 1st in receiving touchdowns and 6th in receiving yards. He also had the highest yards per reception average of any player with 1,000 receiving yards
  • Allen Hurns also hit the 1,000-yard mark, and had the 6th highest yards per reception average of any player with 1,000 receiving yards. Hurns and Robinson were one of just four duos (Jets, Broncos, Cardinals) to have two players gain 1,000 receiving yards.

That’s an impressive trio by any standard, but what’s incredible is that Hurns was born in November of 1991, and he is the oldest of the three! So how young is the Jaguars passing attack compared to other teams? I have decided to create a passing yards-weighted age grade for each passing attack. And in doing so, I chose to count passing yards and receiving yards equally, which of course has the effect of making the quarterback(s) equal to half of the team’s passing game. I’m OK with that.

AV-Adjusted Team Age (Offense) from 2012-2015

Background:

In 2012, the Jaguars went 2-14 with an offense centered around Blaine Gabbert/Chad Henne, Maurice Jones-Drew, Cecil Shorts, and Justin Blackmon. Since then, the team has been rebuilt, and gotten better and younger. Among offensive players, only Marcedes Lewis was on the team during each of the last four years. I’ll have more on the Jaguars tomorrow, but given the way the Jets have moved from young and bad to old and good, I think that’s the more interesting team to analyze today.

Here’s how to read the table below. In 2012, the Jets offense had an age-adjusted AV of 26.9; that dropped to 26.4 in 2013, then rose to 27.5 in 2014 and up to a league-high 29.2 last season. That’s an average of 27.5, but more interesting (to me) is the variance of 1.1 years. [click to continue…]

2015 AV-Adjusted Team Age

In each of the last four years, I’ve presented the AV-adjusted age of each roster in the NFL. Measuring team age in the NFL is tricky. You don’t want to calculate the average age of a 53-man roster and call that the “team age” because the age of a team’s starters is much more relevant than the age of a team’s reserves. The average age of a team’s starting lineup isn’t perfect, either. The age of the quarterback and key offensive and defensive players should count for more than the age of a less relevant starter. Ideally, you want to calculate a team’s average age by placing greater weight on the team’s most relevant players.

My solution has been to use the Approximate Value numbers from Pro-Football-Reference.com.  The table below shows the average age of each team, along with its average AV-adjusted age of the offense and defense. For the second year in a row, the Jaguars and Rams were the two youngest teams in the NFL; this year, though, the team formerly known as St. Louis took the top spot.

The average AV-adjusted team age last season was 27.1 years; the Rams (25.6) and Jaguars (25.8) were the only teams below 26, while the Jets (28.2) and Colts (28.6) were the only teams above 28 years. Here’s how to read the table below, using the St. Louis line: the Rams were the youngest team in the NFL in 2015, with an average age of 25.6 years as of September 1, 2015. The team’s offense had an AV-adjusted average age of 25.0, the youngest in the NFL, while the defense was at 26.0, the second-youngest. [click to continue…]

Farewell to one of the greats

Farewell to one of the greats

Detroit Lions superstar wide receiver Calvin Johnson has likely retired. He had a pretty incredible six-year peak: Megatron gained 8,548 receiving yards in his last six years, the most by any player during their age 25-30 seasons. I don’t think there’s much of a debate that Johnson is a Hall of Famer, although I do think he’s not quite an inner circle member of the Hall.

The big reason for that is Johnson’s numbers have always been inflated by playing on a pass-happy team.  I’ve looked at this before, but (a) those numbers are now two years stale and (b) I want to use a different methodology today. So here’s what I did:

1) Calculate the number of pass attempts per game for each team in every season.

2) For the top 200 players, I then calculated the number of career games for that player.

3) Then, in each season, weight the number of team pass attempts per game by the percentage of games that player played relative to his entire career. For example, Johnson played 11.9% of his career games in 2012, and that year, the Lions threw 46.3 pass attempts per game. Therefore, for Johnson’s career, 46.3 pass attempts per game will be given a weight of 11.9%. Do this for every season of each player’s career, and you will derive the average pass attempts per game for that player. [click to continue…]

In 2015, the average points differential was just 11.06 points per game.  That may not mean much in the abstract, but it’s the lowest in 20 years.  Take a look:

pt diff 1950

What was driving the close games this year?  It’s mostly because the “losing teams” wound up scoring more points, but the average points scored by the winning team did dip slightly in 2015, too: [click to continue…]

Yesterday, I posted some graphs on league-wide passing distribution. In that post, I noted that tight ends grabbed about 16% of all receiving yards in 2002-2003, but that number has increased to over 20% in recent years.  But that’s just receiving yards: as you might expect, targets and receptions have seen a similar climb:

te rec tar
But more targets aren’t the only thing driving the increase.  Tight ends are also averaging slightly more yards per catch, too.  That increase has come despite the general decrease in yards per completion, so this may be a sign that tight ends are more athletic than they were 15-20 years ago, and that teams are sending them on more downfield rights.  In addition, catch rate has also been increasing, although in a more volatile way; still, tight ends are catching more passes, at higher rates, and for more yards.  In the picture below, yards per reception is plotted against the left Y-Axis, and catch rate is plotted against the right Y-Axis.
tar catch rate

Whatever the reason, tight ends seem to be a larger part of NFL offenses they were a decade ago, and for good reason: they’re getting better.

Yesterday, Bob Ford wrote DeMarco Murray and, how his 2014 season stands out as a career outlier. Today, I want to look at where it stands among the biggest year-to-year declines.

I looked at all players who rushed for at least 5 games in consecutive years, and rushed for at least 60 yards per game in the first season. For example, Murray rushed for 1,845 yards in 2014, an average of 115.3 yards per game. Last year, in 15 games, Murray averaged only 46.8 rushing yards per game. That’s a dropoff of 68.5 rushing yards per game, which is the second most in NFL history. The first? That honor goes to Lee Suggs.

Suggs was a star at Virginia Tech, rushing for 27 touchdowns in 11 games as a sophomore at Virginia Tech before tearing his ACL as a junior. In his senior year, he had another great season, rushing for 1,325 yards and 22 touchdowns. He was a 4th round pick of the Browns in 2003, where he served as the team’s backup. In ’04, he stole the job from William Green, and rushed for over 100 yards in each of Cleveland’s final three games. He averaged 74.4 rushing yards per game in ’04, but lost his job to Reuben Droughns in ’05. As a result, Suggs saw his average decline by 72.5 yards per game, an even more dramatic dropoff than Murray. [click to continue…]

2015 Billick/Coryell Team of the Year

In 2014, I came up with the Billick Index and the Coryell Index, which provide a simple measure of the degree to which a team is one-sided.

Let’s use the 2015 Broncos as an example. Denver’s offense scored 32 touchdowns this year, while the average offense scored 37.7. As a result, Denver’s offense was 5.7 touchdowns below average. Meanwhile, the defense allowed only 29 touchdowns, meaning the Broncos were 8.7 touchdowns below average here. Add those two together, and there were 14.4 fewer offensive touchdowns scored in Denver games than in the average 16 games in 2015.

That would put Denver pretty high on the Billick Index, which measures touchdowns scored at lower rates than average. The strongest Billick Index team was the Rams, who finished in the bottom five in offensive touchdowns scored and whose defense ranked in the top five in touchdowns allowed. There were just 55 touchdowns scored in St. Louis games this season.

But the Rams were not the most extreme team this year. Consider that the Saints allowed more touchdowns to opposing offenses — 57 — than offensive touchdowns scored in Rams games on both sides of the ball! [click to continue…]

2015 Playoff Game Scripts Data

With the playoffs over, let’s take one last look at Game Scripts data from the 2015 season. Some high-level notes:

  • In the wild card round, all four road teams won. No road team won another game in the postseason.
  • Just two teams won playoff games this year with negative Game Scripts: the Broncos against the Steelers (-0.5) and the Seahawks against the Vikings (-2.5). The Steelers led 10-6 for much of the 2nd quarter, and 13-9 in the third quarter. In fact, Denver trailed 13-12 until there were three minutes left in the game. The frigid game in Minnesota was a tale of three quarters… and a disastrous fourth. The Vikings entered the 4th quarter up 9-0, but Seattle scored the final points of the game to emerge with a 10-9 win.
  • The most pass-happy game by a winning team in the playoffs? That came by the Patriots in the division round against the Chiefs. Even without adjusting for Game Script, it was pass-happy, but a 76.4% pass ratio with a +8.3 Game Script is incredible. Remember, New England attempted a pass on 24 of its first 26 plays, and the Patriots finished with just 10 non-kneel runs.

Below are the 2015 playoffs Game Scripts data: [click to continue…]

How do the Broncos stack up with the best playoff defenses?

The Broncos just capped off a run that saw the defense carry Peyton Manning and a below-average offense to a Super Bowl title. Denver held the highest scoring team in the league to just 10 points in the Super Bowl. As a result, debate ensued as to where the Broncos ranked among other great Super Bowl winning defenses. And just last week, Chase looked at the net points allowed by each Super Bowl champion. [click to continue…]

Guest Post: Adam Harstad on Sammy Watkins

Today’s guest post comes from Adam Harstad, a co-writer of mine at Footballguys.com. You can follow Adam on twitter at @AdamHarstad.


It’s probably not really news at this point, but the 2014 WR class has been pretty good. How good?

Well, Jarvis Landry just broke the old record for receptions through two seasons… by 26 grabs. Jordan Matthews joined the short-list of receivers to top 800 yards and 8 touchdowns in each of their first two seasons, (a list which, since the merger, contained just five names prior to last year). Mike Evans joined Randy Moss and Josh Gordon as the only players in history with 2200 receiving yards through their age 22 season.

Allen Robinson just became the youngest player to top 1400 yards and 14 touchdowns in the same year. And 2nd-4th on that list? Randy Moss, Jerry Rice, and Lance Alworth.) Outside of the first two years of the AFL, no undrafted receiver in history has produced more yards or touchdowns in his first two years than Robinson’s teammate, Allen Hurns. [click to continue…]

Despite a fourth trip to the Super Bowl, 2015 has been the worst year of Peyton Manning’s storied career. Statistically speaking, he has never been worse, even as a 22 year old rookie starting all sixteen games for a 3-13 team.1 Relative to league average, Manning produced the worst completion rate, yards per attempt, touchdown rate, interception rate, passer rating, and adjusted net yards per attempt of his career.2 Manning ranked last among the 36 qualifying passers in Adjusted Net Yards per Attempt. And his normally stellar sack rate also took a hit, with the second worst output of his career (behind only 2001).3

If we look to advanced metrics to try to uncover some hidden gem about his performance that may be overlooked by standard box score stats, we don’t have much luck. ESPN’s QBR (which only goes back to 2006, mind you) takes into account far more than any other popular metric, and it normally adores Manning. From 2006-2014 (excluding 2011, obviously), Manning ranked 1st, 3rd, 1st, 1st, 1st, 1st, 2nd, and 3rd in Total QBR.4 This year, he ranked 30th with a subpar 45.0 rating.

Football Outsiders’ DVOA and DYAR don’t do Manning any favors either. Not only was 2015 by far the worst season of his career by both metrics, it was also the only below average season of his career. From 1998-2014, his average season was 32.47% better than average by passing DVOA. His worst season by the metric was a 7.70% effort as a doe-eyed rookie. Over that same period, he averaged 1,664 passing DYAR per season, and his average season was worth 2.89 DYAR per pass.5 This year, Manning was 26.00% below average, as measured by DVOA, and he lost 328 DYAR from his career total. His -0.95 DYAR per play was easily worse than his previous low of 1.18 in his inaugural season.

If the stats aren’t enough, the infamous “eye test” also backs up the belief that this was Manning’s worst-ever season. He struggled to jive with Gary Kubiak’s offense, especially when asked to run bootlegs and throw on the run. His limited power to make pre-snap adjustments, in concert with his decreased mobility, resulted in him taking more abuse in the pocket than he ever had before.6 He threw errant passes and made uncharacteristically poor decisions, causing him to lead the league in interceptions until week 17, despite missing six games. He struggled with nagging injuries, had the worst game of his entire career, and was benched for an inexperienced and marginally talented fourth-year backup. [click to continue…]

  1. A team that also went 3-13 the prior year and earned the right to draft him first overall. []
  2. Using Pro Football Reference’s Advanced Passing Index Scores as my measurement of choice. []
  3. Of course, being Peyton Manning, he was still better than average; his Sack%+ score was 110 in the regular season. []
  4. Among all quarterbacks with at least 224 action plays. His second place rank in 2013 becomes a first place rank if you finagle the threshold to exclude Josh McCown’s 269 play, 85.2 QBR bout. []
  5. Using the average of his averages rather than a weighted average of all DYAR on all pass plays. The point here is to show his average season, not his average performance over the course of his career. []
  6. I covered this in more detail after his poor week 2 performance. You don’t have to call me a prophet, but I won’t stop you. []

Manning/Brady 18 will use Manning's uniform number instead of Roman Numerals

Manning/Brady 18 will use Manning’s uniform number instead of Roman Numerals

Tom Brady and Peyton Manning have now played seventeen games against each other. Brady has posted an 11-6 record against Manning, which tends to fuel some of the Brady/Manning narrative. The beginning of their “rivalry” was dominated by Brady and the Patriots: from 2001 to 2004, New England went 6-0 against Indianapolis, including two playoff wins in the snow in Foxboro.

Those four seasons anchored the narrative for the 15-year rivalry of the two players. Since then, Manning has a 6-5 record against Brady, including a 3-0 mark in the playoffs. Each player has also won “only” one Super Bowl despite the two quarterbacks dominating the AFC for most of the last decade (Manning, of course, could win another next week).

The table below shows the statistics from both players for each of the 17 head-to-head games: [click to continue…]

This pass probably wasn't completed.

This pass probably wasn’t completed.

In the NFC Championship Game, Carson Palmer was really bad.  He completed 23 of 40 passes for 235 yards, with three sacks that lost 8 yards.  That by itself is not very good — it translates to a 5.3 net yards per attempt average — but the real damage came when it comes to turnovers.  Palmer threw one touchdown againt four interceptions, giving him an Adjusted Net Yards per Attempt average of just 1.56.  And even that inflates things a bit, as Palmer also fumbled twice, with both fumbles being recovered by Carolina. On the season, Carolina allowed 4.46 ANY/A to opposing passers, the best in the NFL, so that does mitigate things a bit.  As a result, Palmer’s game is considered -125 ANY below expectation, because he was 2.9 ANY/A below expectation over 43 dropbacks.

That’s bad, but nowhere near as bad as the worst performance from even this year’s playoffs (Brian Hoyer) or the last Cardinals playoff loss (thank you, Ryan Lindley).  But the reason Palmer’s performance appeared so bad was precisely because it came from someone like Carson Palmer, and not a Hoyer or a Lindley.  Palmer, after all, was arguably the best passer in the NFL this season.  He led the NFL in Adjusted Net Yards per Attempt, at 8.11, which was 2.14 ANY/A better than league average.

In 1974, Terry Bradshaw was not very good. He threw for just 785 yards on 148 pass attempts, while throwing only 7 touchdowns against 8 interceptions. That translates to a 2.92 Adjusted Net Yards per Attempt average, which is terrible even for 1974. He ranked 25th in ANY/A among the 32 quarterbacks with at least 120 pass attempts. Given the league average of 3.91, that means Bradshaw finished the year with a Relative ANY/A of -0.99.

That’s the worst of any quarterback who wound up winning the Super Bowl. But that doesn’t mean Bradshaw wasn’t a big part of why Pittsburgh won its first title. He was excellent in the team’s three playoff games, particularly in Pittsburgh’s first win. [click to continue…]

Courtesy of Bryan Frye, let’s look at some graphs of the four quarterbacks in the conference championship games. The stat we will be using today is Total Adjusted Yards per Play, which is like ANY/A on steroids.

First, let’s start with Cam Newton. His Total Adjusted Yards per Play is in blue; the average TAY/P allowed by his opponent each week is in black. As you can see, in 6 of 17 games, he was below-expectation, but he’s been above-expectation in five of his last six games. (Note that for each quarterback, the bye week is included, and the division round matchup is plotted below as Week 18.) [click to continue…]

Guest Post: Marginal YAC, 2015 in Review

Adam Steele is back to discuss Marginal YAC, this time in the context of the 2015 season. You can view all of Adam’s posts here.


Marginal Air Yards: 2015 Year In Review

Today I will be updating my Marginal Air Yards metric for the now completed 2015 season. New readers who aren’t familiar with Marginal Air Yards can get up to speed by reading my three part intro-series and 2014’s year in review.

There were 44 quarterbacks who threw at least 100 passes in 2015, and they are ranked by mAir below: [click to continue…]

The 2015 regular season is in the books, and all the relevant stats are at our disposal to poke and prod as our hearts desire. Chase already discussed the fact that, statistically, this has been the best passing season in NFL history. League and team passing records fell on a seemingly regular basis, and a few receiving records were in serious jeopardy by season’s end.1 [click to continue…]

  1. We probably all know by now that Julio Jones and Antonio Brown became just the third and fourth receivers ever to break the 1,800 yards mark in a single season. It’s also pretty common knowledge that the two dynamic receivers also tied for the second most receptions in a single season. However, what you won’t hear in the mainstream is that Jones happened to break one of the more significant single season records when he hauled in his 93rd receiving first down in week 17. []

Houston/Kansas City

Last year, after the Ryan Lindley disaster in the playoffs, I looked at the worst passing performances in playoff history.  At the time, Lindley had the 9th worst passing game ever.  Well, now it’s the 10th.

Against Kansas City yesterday, Brian Hoyer completed 15 of 34 passes for just 136 yards with 0 touchdowns and 4 interceptions. He also lost a fumble on his three sacks, which lost 17 yards.  Calculating Adjusted Net Yards per Attempt doesn’t factor in fumbles, but Hoyer still finished with -68 Adjusted Net Yards for Brian Hoyer on those 37 dropbacks.   That’s a -1.84 ANY/A average.  On the season, Kansas City allowed 4.91 ANY/A.

Week 17 Game Scripts: The Patriots Get Run Heavy

Week 17 often brings about weird results, and this year was no different. Seattle posted a Game Script of +17.6 against Arizona, which is an extreme outlier. Consider that the Cardinals had just one negative Game Script in the team’s first 15 games, a -3.8 score against St. Louis back in week 4.

Oh, and the Patriots do something really crazy (for them), but we’ll get to that in a bit. For now, the week 17 Game Scripts data. Note that this page is now updated to include the Game Scripts data from each of the 256 games this season. [click to continue…]

This week at the New York Times, a look at how this season was, yet again, the best passing season in history:

First, a look at quantity. N.F.L. teams averaged 35.7 pass attempts per game, the most in league history, breaking the record of 35.4 set in 2013. Teams used those attempts to also set per-game records for completions (22.5) and passing yards (243.8). Passing touchdowns per game were also at a new N.F.L. high. The record had been 1.63 a game, set, remarkably, in 1948. The league had been inching toward that mark — teams averaged 1.57 and 1.58 passing touchdowns per game in 2013 and 2014 — before surpassing it with 1.64 passing touchdowns per game in 2015.

For the first time in N.F.L. history, 12 quarterbacks threw for 4,000 yards. In addition, 11 quarterbacks threw at least 30 touchdown passes; that breaks the record of nine set last season. Before 2014, no N.F.L. season had more than five quarterbacks with at least 30 touchdown throws.

Teddy Bridgewater and Quarterback Help

No offense has had it easier this year than the Denver Broncos. What do I mean by that? Denver ranks 4th in points allowed, at 276, but that’s a little misleading. The Broncos have thrown three pick sixes, all from Peyton Manning, and those have put 20 points on the scoreboard (one pick six was followed by a failed two-point attempt). In addition, Denver’s defense/special teams has scored six touchdowns. Those obviously go in the “Points Scored” column for Denver, but in terms of the offense, they didn’t earn those points. So instead, let’s subtract all non-offensive touchdowns scored by the Broncos by the points allowed by Denver. Do that, and the Broncos defense has allowed 214 net points, after excluding pick sixes and crediting the defense for non-offensive touchdowns.

That’s the fewest in the NFL. Last offseason, I wrote an article about Andrew Luck and quarterback help.  It was pretty basic, but I found it interesting enough to recreate today.  Here is the methodology: [click to continue…]

Nobody wants to watch this Saints defense with their eyes open

Nobody wants to watch this Saints defense with their eyes open

In short, maybe.

New Orleans has allowed 4,217 passing yards this year (which includes yards lost by the opposing team on sacks) on 538 dropbacks, which is already pretty bad.  That translates to a 7.84 Net Yards per Attempt allowed average, which is the worst in the NFL by half a yard per attempt.  But where things get really bad is in touchdowns and interceptions.  New Orleans has allowed an unbelievable 43 passing touchdowns through 15 games, the most in NFL history. In addition, the Saints have intercepted just 8 passes, tied for third fewest in the league this year.

That translates to an 8.77 Adjusted Net Yards per Attempt average, after giving 20 yards for each touchdown pass and subtracting 45 yards for each interception.  That is, by a decent measure, the worst rate in NFL history.  The current record belongs to the 0-16 Detroit Lions, who allowed 8.53 ANY/A.  Only three other teams — the ’81 Colts, the ’69 Saints, and the ’63 Broncos — have even allowed 8.00 ANY/A over a full season.
