2011 Adjusted Games Lost

EXCERPT:
Let's start with a few teams -- other than Indianapolis -- that had their seasons short-circuited by injury.
With their 110.0 AGL, the 2011 St. Louis Rams became the second-most injured team since 2002. Only the 2009 Buffalo Bills had it worse off. And like those Bills, the main contribution to the 2011 Rams AGL came from their defensive backfield, where their top three cornerbacks -- four if you count early-camp casualty Jerome Murphy -- were already out for the year by Week 10.
Also not helping matters were another year of carnage at wide receiver (29.0 AGL after 26.4 in 2010) and 5.7 AGL for Sam Bradford. With injuries affecting the (offensive and defensive) passing game this much, it's no wonder St. Louis went from the cusp of the playoffs to winning only two games.
The team that saw the largest absolute increase in AGL (from 10.0 to 65.5) was Kansas City, so it's no surprise they lost three more games last season than in 2010. The interesting thing about the Chiefs is that about 60 percent of their AGL came from only four (albeit vital) players: Matt Cassel, Jamaal Charles, Tony Moeaki, and Eric Berry. Otherwise, they were an incredibly healthy squad: If not for those four significant losses, they would have ranked third overall.
Moving on to teams that saw their win totals clearly benefit from increased health in 2011, we have the two playoff participants from the NFC North. Detroit went from a team ranked in the middle of the AGL pack in 2010 to one of the healthiest teams in the league last season. Most of that good fortune came at quarterback, where Matthew Stafford's newfound durability resulted in a full season's worth of improved AGL at the position.
Classifying Green Bay as a team helped by increased health seems a bit odd given that they were coming off a Super Bowl championship in 2010. But remember that they only won 10 games that year. The same way improved health can be the catalyst for a rise from mediocrity (as in Detroit), it can also play a role in a 10-6 team improving to 15-1. Healthy seasons from Jermichael Finley and Ryan Grant dropped AGL at tight end and running back from 26.6 to 1.3, which likely contributed to a 24.5% improvement in offensive DVOA.
