The most efficient runner in NFL history? That depends.
Jamaal Charles is now a Denver Bronco, making him the second superstar running back in two weeks to join a new team at the tail end of his career. In his prime, Charles was a very good receiver and a player that could be the centerpiece of an offense. However, he will likely be remembered for a singular skill: rushing efficiency.
Charles has a career YPC average of 5.45, easily the best in history among running backs in the NFL. That number is at least a little misleading. While rushing efficiency has not soared the way passing efficiency has, we are currently in a high-YPC environment. Two years ago, I calculated era-adjusted yards per carry: at the time, Charles was at 5.49, while the league average was 4.21. For reference, the league average during the careers of Jim Brown, Gale Sayers, and Barry Sanders was 4.08, 3.95, and 3.93, respectively.
I am not a big fan of yards per carry as a statistic, but hey, it’s still interesting trivia. It’s a little silly and mostly an academic exercise, but let’s pretend that we replaced every Charles rush attempt with a league average rush attempt. How much worse off would Kansas City have been? Well, a whole lot. Let’s use his 2010 season as an example. He had 230 carries for 1,467 yards, producing an incredible 6.38 YPC average. The league average that season was 4.21, meaning he was 2.17 YPC above-average. Given his 230 carries, we would have expected him to rush for just 968 yards, meaning he produced 499 rushing yards above average. And for his career? Charles is at +1657. [click to continue…]
This week at the New York Times, I look at how the Chiefs have gone from worst to first:
The Chiefs have found success in an unusual way. In the modern N.F.L., the best teams tend to be the best passing teams, but Kansas City has managed to succeed with a mediocre passing attack thanks to a great defense, excellent field position, a dynamic offensive talent and an easy schedule.
Kansas City’s defense has been dominant, ranking first in both points allowed and passer rating allowed. Bob Sutton, a defensive coach with the Jets from 2000 to 2012, has done a remarkable job transforming a defense that struggled in 2012 into the league’s best in 2013.
Inside linebacker Derrick Johnson made the Pro Bowl in each of the past two seasons and has been strong again this season, but he is just the third best linebacker on the team, behind outside linebackers Justin Houston and Tamba Hali.
Houston has 10 sacks and 2 fumble recoveries. Hali has nine sacks and four forced fumbles, and he has returned an interception for a touchdown. Hali has 40 hurries, the most in the N.F.L., according to Pro Football Focus. No. 2 on that list? Houston, with 28.
Houston and Hali made the Pro Bowl last year, but they are reaching new heights this season in part because of a greatly improved defensive line. Dontari Poe, Tyson Jackson and Mike DeVito were question marks entering the season, but the three have produced remarkable results through seven weeks.
I also discuss how Alex Smith has the lowest average depth of pass this season, but still has a mediocre completion percentage:
Smith’s average pass has traveled just 6.23 yards past the line of scrimmage this year, the shortest of any passer. Quarterbacks who throw shorter passes tend to produce high completion percentages — Smith, who frequently checked down with San Francisco, too, completed 70.2 percent of his passes last year — but this season, Smith has completed only 58 percent of his passes with Kansas City.

How bad were the Chiefs last year?
- Kansas City went 2-14, tied for the worst record in the league with Jacksonville. Since the Chiefs faced an easier schedule, they received the first pick.
- With an Simple Rating System score of -14.0, Kansas City had the worst SRS rating in the league. They ranked 32nd in points scored and 25th in points allowed, leaving them 32nd in points differential. With a slightly easier than average schedule, that left them 32nd in the SRS, too.
- The Chiefs ranked in the bottom three in both NY/A and NY/A allowed.
- With a -24 turnover differential, K.C. tied several other teams, including the 2012 Eagles, for the third worst turnover differential since 1978.
- Brian Burke ranked the Chiefs 31st overall, 31st on offense, and 31st on defense, just edging out the Jaguars (who ranked 32nd on offense and 30th on defense).
- Kansas City finished 32nd in Aaron Schatz’s efficiency rankings, as Football Outsiders ranked them 31st on offense, 30th on defense, and 22nd on special teams.

The good Charles showed up against the Saints.
A couple of weeks ago, I heard my buddy and co-worker Sigmund Bloom
say on the Footballguys Podcast
that Jamaal Charles
was having one of the craziest seasons ever. As Sigmund noted, Charles has been an incredibly frustrating fantasy player. This year, he had three games with 10 or fewer rushing yards… and he also became the first player in NFL history with two games with over 225 rushing yards
in the same season.
Did you know that Kansas City finished 2012 fifth in carries? Under Todd Haley, Chiefs fans and fantasy football players were constantly frustrated by Thomas Jones, who Haley seemed to always find a way to give an extra ten carries to. This year, under Romeo Crennel, Peyton Hillis was the complementary back, but he was not nearly as predatory. Still, while Charles finally received the lion’s share of the carries, he was once again an inconsistent fantasy player.
Take a look at Charles’ weekly game logs:
That’s a pretty incredible distribution, but how crazy is it?
I looked at the standard deviation of every game by every player in a season with at least 1,000 rushing yards from 1960 to 2011. As it turns out, Charles has had one of the most inconsistent seasons ever. While he gained 1,509 rushing yards, he had a standard deviation of 71.4 yards. That may not mean anything to you in the abstract, but it would place him as the 4th most inconsistent back since 1960.

This week at the New York Times I looked at some record-breaking performances from week 16.
Sunday was a record-setting day in the N.F.L. In case you missed it …
- The rookie Minnesota Vikings kicker Blair Walsh connected on a 56-yard field goal in the second quarter against the Texans, making him the first kicker with nine field goals of 50 yards or longer in a season. Even more impressive: Walsh is 9 of 9 from 50-plus yards this year.
- Kansas City rushed for 352 yards against the Colts, easily breaking the record for rushing yards gained in a losing effort and also for rushing yards differential in a loss. How do you lose when you rush for so many yards? Brady Quinn threw an interception that was returned for a touchdown and threw another pick in the Colts’ end zone. Another Chiefs drive ended on a fumble inside the Colts’ 20-yard-line. But the turning point of the game may have been when Quinn was stuffed on a fourth-and-1, one of the few times in the game that the Colts’ run defense won the battle at the line of scrimmage.
- In the same game, Jamaal Charles recorded the 750th carry of his career, giving him enough rushing attempts to be eligible for the career yards-per-carry title. Jim Brown averaged 5.22 yards per carry during his Browns career. That’s now second highest among running backs in N.F.L. history. Charles has a mind-boggling 5.82 average gain over his five-year career.
- Brown might take a back seat to another running back this season. Buffalo’s C.J. Spiller has averaged 6.48 yards per carry this year on 183 carries, the highest single-season average of any player with that many carries. The previous record holder was Brown, who averaged 6.40 yards per rush in 1963.
- It’s been another remarkable season for Atlanta’s Tony Gonzalez, but he actually was nudged out of the record books this weekend. In 2004, Gonzalez set the single-season record for receptions by a tight end with 102, but Dallas’s Jason Witten caught his 103rd pass of the season in overtime against the Saints on Sunday.
- The Seattle Seahawks have outscored their last three opponents, 150-30. That 120-point margin of victory is the largest differential in a three-game span in 70 years. In 1942, the Chicago Bears won three straight games and did it with a combined 127-7 score; the year before, Chicago outscored its opponents, 136-14, over a three-game stretch.
Mega Record for Megatron
Of course, the most noteworthy individual record to fall this past weekend was Jerry Rice’s single-season receiving record of 1,848 yards. Calvin Johnson needed only 15 games to break the record Saturday night, and with 1,892 yards, he has a good chance of becoming the first N.F.L. receiver to hit the 2,000-yard mark.
With 225 yards against the Falcons, he also became the first player to gain 100 receiving yards in eight straight games and to collect 10 receptions in four straight games. For Johnson, it was his fifth career game (including the postseason) with at least 200 receiving yards, tying him with Lance Alworth and Rice for the most 200-yard games since 1960.
Detroit has averaged 47 pass attempts per game, and will set the single-season record for attempts on its 12th pass attempt Sunday. Most of those passes have come from the right arm of Matthew Stafford, who threw 663 passes in 2011, (now) the fourth-highest number ever. On his seventh pass in Week 17 against the Bears, he’ll set the record, and he needs just 15 passes to become the first quarterback with 700 pass attempts in a season.
