Stats don't often tell the whole story, but most are relevant when put into context. Here are four stats related to the Philadelphia Eagles that help explain why they stand where they do at the six-week mark of the 2012 NFL regular season.
13.8: That's how many times the Eagles offensive line is allowing pressure on a per-game basis, according to Pro Football Focus. Michael Vick was already one of the most pressured quarterbacks in the league last year, but in 2011, Philadelphia only gave up 10.1 pressure plays per game. Last year, Vick was pressured on a league-high 39.8 percent of dropbacks. This year, that number has somehow increased to 45.4. It's just amazing Vick has survived, but this pace isn't sustainable.
3.0: That's Philadelphia's sack percentage, which Pro Football Reference calculates as how often a defense takes down an opposing quarterback on a per-snap basis. That number ranks third last in football and represents a dramatic drop-off from 2011, when the Eagles led the NFL in this category with a sack percentage of 8.8. Have offenses figured out how to deal with Jim Washburn's Wide 9? How else do you explain why the healthy Eagles defensive line is getting sacks about one third as often this year as it was last year?
Which defensive problem is hurting Philadelphia most?
6.7: That's how many tackles the Eagles are missing per game, according to Pro Football Focus. While it feels as though they haven't been tackling all too poorly this year, that number is actually only 0.1 percent below their per-game average from 2011, which was second worst in football. I suppose they haven't had as many glaring or embarrassing whiffs, but it's still concerning that—even with a revamped linebacking corps—they're still struggling to wrap up. Rookie Mychal Kendricks has already missed 10 tackles, which is more than any other outside linebacker in the league.
31.6: That's the average yard line where the Eagles' first six opponents have started their drives, which according to Football Outsiders, ranks second last in the NFL. For comparison's sake, the unbeaten Falcons lead the league here at 23.1. That's an 8.5-yard gap. The major issue is that the Eagles only start on the 23.5-yard line, which ranks 29th. A lack of effectiveness on kickoffs, punts, kick returns and punt returns is killing them.
