Is The Eagles Offensive Line Quietly Even Worse Than Last Year?

The Eagles rushing attack is pretty great.

The offense leads the league in total rushing yards (2140) and average per carry (5.0). Football Outsiders grades them out as the top DVOA rushing offense with +20.1%, head and shoulders above second-place Dallas at +10.9%. A piece of that action has come on quarterback runs. Michael Vick is second in the NFL in rushing DYAR despite having only played in parts of six games. Banged up at age 33, he has the highest rushing DVOA of his career, a ridiculous +68.1%. Even slowpoke Nick Foles places 7th in rushing DYAR and 9th in DVOA, showing the power of the zone read.

But the bulk of the rushing offense comes down to one man: LeSean McCoy. The first back to cross 1000 yards, he's second in the league in DYAR and has already surpassed his personal season rushing record. During the Snow Bowl, he set a new franchise single-game rushing record. However, he also took some flak last month from his coach Chip Kelly, who told the press that he pushes Shady to not dance around quite so much:

"I think LeSean is trying to press too much and trying to hit a home run on every play instead of letting it develop," Kelly said.

The comment was fairly innocuous, as any observer could point out a couple plays every game where McCoy tries to out-juke just one too many defenders, or cut back one too many times. But ultimately McCoy is a Barry Sanders-esque force of nature in the backfield, and he's bailing out Chip's offense and his blockers up front much more than the other way around.

See, the truth according to the advanced stats runs somewhat contrary to the conventional wisdom. Not that anyone is particularly discounting McCoy's contribution to the offense. But there has been a lot of praise heaped on the zone read and a rejuvenated offensive line for the success of the run game. It's not completely misplaced. Certainly we've seen the Jason Peters, Evan Mathis and Jason Kelce dominate blocks at times. Todd Herremans appears to be fading with age, and Lane Johnson makes some rookie mistakes, but they're important athletic pieces in the blocking scheme.

But ultimately, the advanced offensive line stats don't look particularly good:

Since 2010, when McCoy took over as the featured back, the rushing attack has been stellar. High per-rush averages, great power success (that's short yardage, high leverage plays), and elite 2nd level and open field gains. The consistency of those stats is shocking compared to the overall decline in Football Outsiders' signature stat of Adjusted Line Yards. That metric weights runs by distance, attempting to isolate the offensive line's performance over the early yards vs. the largely running back-driven yards down the field.

McCoy has always generated a healthy performance bump above what his offensive line provides him, but this year is the greatest difference yet. Some of that is a higher rushing average than the last two years, but Eagles running backs are actually behind their 2010 pace. The difference is that the offensive line has only "generated" 3.47 yards per rush, 0.6 yards per rush less than 2010. The gradual decline over the last three years comes despite no major change in power or stuffed rank. And the 2nd level and open field yards are as good as ever for McCoy.

Plus, the offensive line isn't doing so hot in pass protection either. The adjusted sack rate is actually worse than last year, despite a distinct lack of starting games by noted turnstile Danny Watkins.

None of these stats are perfect, but the overall picture isn't jiving with the public narrative of a rejuvenated offensive line. And that's partially to be expected. The Eagles had the eight-oldest starting offensive line coming into the season, despite starting a 23-year-old rookie. The Giants are the only other team to rely on three starters over 30. Normally you would worry about injuries with an aging offensive line, but due to either #sportscience or good luck, the Eagles front five have been remarkably injury-free. They just haven't been as productive.

Despite controlling their own playoff destiny, this team has a lot of obvious holes. But when everyone's screaming for more pass rushers and defensive backs this offseason, don't be surprised if the Eagles make a push for young offensive line help. It's secretly one of the team's largest problems.

The Eagles Still Aren't Great, But That's OK

Before the season started, I set my expectations for 2013 at a reasonable level: an improvement from last year's disaster squad and a foundation built for future growth. As I said then, most teams as bad as the Eagles improved, on DVOA terms, by an average of about 12%. I anticipated something along those lines, with a slight record improvement but certainly no mention of playoffs.

Obviously, I was wrong. Before Sunday's loss, the Eagles had improved by nearly 33% in DVOA, one of the best turnarounds ever. That will cool slightly this week, but the team still has the inside track on a playoff spot, something most people (including Jeffrey Lurie) never expected to happen so soon.

But Sunday's game reminded us that this squad -- or at least half of it -- is still a work in progress. Chip Kelly's offense is gangbusters, even if it can sputter out for stretches. On a "bad day," Nick Foles threw for 428 yards on 30 for 48 attempts, 3 TDs and 1 INT. Plus he ran the ball 5 times for 41 yards to boot. LeSean McCoy only got 8 carries, but still finished with over 100 yards from scrimmage. DeSean Jackson had nearly 200 receiving yards plus an end-around touchdown called back due to penalty. Oh, and rookie tight end Zach Ertz ended the day with 57 yards on 6 receptions, including a one-handed TD grab. No big problems here.

The defense is still messy, though. As I've said before, you don't have to be an elite quarterback to find the holes in Billy Davis' scheme (Hint: look for the safeties). A smart, patient, accurate player will pick this secondary apart. That's what happened when the Eagles D was skinned alive during the three-game stretch against Philip Rivers, Alex Smith, and Peyton Manning. Since then, during the team's 7-2 run, opponents never scored more than 21 points. 

The great nine-game run leading up to Sunday seemed to be the defense gelling, but most of it was the horrendous, mistake-prone quarterbacks the Eagles faced. Only two of the QBs the Eagles faced in that span have positive DVOA on the year, and they played one of those in a blizzard. Matt Cassel could easily have been another one of those lightweights, but he did his best 2008 impression, throwing for the 4th-most yards of his career. That came despite the Eagles front seven holding the Adrian Peterson-less Vikings to just 2.4 yards per carry.

Worth noting: Football Outsiders never bought into the Eagles defensive turnaround. While they were bend-but-not-breaking their way to sub-22 point totals, the defense allowed over 350 yards in all but two of the last 9 games. Coming into Sunday, the team ranked 22nd in defensive efficiency, versus 3rd on offense. Even with Denver and Kansas City as past opponents, the Eagles faced the 27th-weakest schedule and registered the highest level of inconsistency in the league prior to this week. Including week 15, the Eagles have the lowest point differential of any division leader.

So again, the Eagles aren't great. If their schedule weren't so easy, including six games against the criminally ugly NFC East, I imagine the team would have finished closer to my "return to 1999" prediction than their current possible outcome of 8-10 wins. If the Eagles win the division, which I now expect them to do either against Chicago with the Cowboys losing again, or in Dallas the week after, they will have vastly overperformed -- despite being only a mediocre overall team.

But that's OK. Even if the Eagles get rolled over by a better wild card team like San Francisco, Carolina, or New Orleans, the season will have been a smashing success, and one to build on in 2014. Kelly's offense still has room to grow next year, and the defensive reconstruction will continue. Until then, enjoy this #housemoney season.

Anticipating the Impact of Todd Bowles

Todd Bowles is 6’2”, 203 lbs. Well, at least he was that big when he played in the NFL as a free safety for eight years.

Normally, the height and weight of a coach wouldn’t matter much. But in the case of Bowles, we can draw a clear line between his frame and his personnel preferences as a secondary coach.

As you can see at right, teams where Bowles has been the secondary coach consistently draft tall defensive backs (the same way Jim Washburn only picked tall defensive ends). In fact, he’s only drafted one defensive back under six feet since 2003, and that was in the seventh round. Clearly, Bowles’s preference is for bigger, more physical players. He probably would not, for example, have endorsed the selections of Sheldon Brown and Lito Sheppard, two 5’10” corners.

More relevant: Asante Samuel is not the type of cornerback Bowles had in mind as his prototypical starter. As I’ve mentioned before, the Samuel trade was about ego, a broken locker room, and justifying the 2011 personnel decisions — not on-the-field performance or the salary cap. But I doubt Bowles was campaigning for Samuel to stick around.

Instead, he’s probably quite content with his starters at cornerback for 2012. Nnamdi Asomugha is 6’2”, 210 lbs and Dominique Rodgers-Cromartie is 6’2”, 182 lbs. Hopefully Bowles can help mold a solid defensive backfield around the two of them. Curtis Marsh also stands to gain quite a lot from the Bowles hire, since his athletic 6’1”, 197 lbs frame would be perfect for his new coach’s system.

On the other hand, Kurt Coleman probably shouldn’t get too comfortable as a starter. I’ve discussed his athletic limitations before, but Bowles may be particularly keen to find someone with a higher ceiling. The counter-example of course, is 5’9” Brandon Boykin, whose selection Bowles must have approved. But perhaps he is willing to make an exception for the physical slot corner, regardless of his size, given the value he presented in the fourth round.

Alright, you’re probably saying, this is fun roster speculation and all, but what does it really mean? I’ll admit, not much right now. We already knew who the likely starters were and presumably Bowles will play whomever is the best in practice, not go simply by their official measurements. The more important question remains: is Bowles really a great coach? Every reporter hailed the addition as brilliant, but I’m less impressed by the fossil record:

The Inadequacy of Opponent Adjustments

Semi-annual blogger Derek Sarley:

VOA is a measure of how well a team has played and DVOA corrects for opponents, so you can throw out any concerns about strength of schedule and say things like “DVOA proves the Eagles have the league’s twelfth-best defense, even if you claim they didn’t play very many teams that were any good.”

Except you can’t. DVOA says nothing of the kind, as we can best demonstrate with a couple of charts. Here’s the first one, plotting this season’s DVOAs against VOAs:

Long story short, opponent adjustments are nice, especially for comparing teams quickly. But DVOA and its ilk will never be able to provide a complete understanding of a single team or unit. Even advanced stats need context.

Time to Unleash LeSean McCoy

LeSean McCoy

As I described yesterday, the odds of the Eagles finishing off the season with only two losses and making the playoffs are very small. Anyone who has watched this team for even a few minutes can tell that this is a below .500 club right now. And I have little hope that the main issues plaguing the team will be fixed any time soon.

But I can be convinced that the Eagles will win on Sunday against the Redskins, in spite of those issues. I think that requires one thing: unleashing LeSean McCoy.

Let me try to illustrate just how great McCoy’s season has been through five games. Only seven running backs in the last 20 years with more than 100 carries in a season have scored higher than 30 percent on Football Outsiders rushing DVOA, a statistic that measures performance above the average player. If McCoy can keep it up, his will be the highest of all of them:

  1. 2011 LeSean McCoy — 39.1%
  2. 2000 Marshall Faulk — 35.0%
  3. 2010 Jamaal Charles — 33.9%
  4. 2002 Priest Holmes — 31.1%
  5. 2003 Onterrio Smith — 30.8%
  6. 2006 Marion Barber — 30.5%
  7. 2004 Larry Johnson — 30.0%

And this isn’t a fluke. McCoy has the highest yards per carry average in the NFL among running backs with at least 30 carries. He is tied for the second-most rushing touchdowns, first all-purpose. This production is despite an offensive line suffering from injuries, poor blocking by rookies and journeyman free agents, and a general inability to gain an inch on short yardage and goal line plays. Oh, and he’s seemingly the only Eagles offensive skill player to not have a fumble. That is a historic season in the making.

Yet, even by Andy Reid’s low standards, McCoy hasn’t gotten nearly enough touches. There are 13 running backs with more rushing attempts. If you look at rushing attempts by team, the Eagles are ranked fifth. But that includes Michael Vick’s 38 scrambles. Take those away, and the Eagles are suddenly 29th.

McCoy was handed the ball only 20 times in the last two games. To let that trend continue against Washington would be a crime. The Redskins have the fifth-ranked defensive DVOA this year, but are just 17th in run defense. Furthermore, it would take the pressure off Vick, expose play-action pass opportunities downfield, and keep the woeful Eagles defense on the sideline.

There is no easier gameplan than pitting your biggest strength against the opponent’s biggest weakness (See: Gonzalez, Tony vs. Eagles LBs). Missing that opportunity with McCoy in week six — and the rest of the season — would be a fire-able offense.
