Mark Ingram has yet to be seriously injured during his time at Alabama, but his previous minor injuries may tell us something.
Ingram was a bit banged up before the Iron Bowl last year, then injured his hip during the game. The Auburn Tigers swarmed to Ingram every time he got the ball, holding him to just 30 yards on 16 carries.
Was it because he wasn't running hard? Or was it Auburn's great defensive scheme?
When Richardson had his chances in the ball game, he did a bit better against the fired-up Auburn squad with 15 carries for 51 yards and a touchdown.
Ingram's 2009 Iron Bowl performance may not tell us how he will react upon his return from injury this season; Ingram is a tough back that has battled through the flu and other sorts of minor injuries and still performed well.
Some of Ingram's reaction to injury may depend on how soon he gets to play. If he is out there in Week 2, there is a good chance we will see him play like the Ingram we saw in the 2009 Iron Bowl, leaving the door open to Richardson.
