Mark will still make a big contribution as best he can, but his play will be missed. Make no mistake about it, you don't lose a player like Mark Ingram from your line up and not miss him (especially, if he misses games beyond SJSU).
However, Bama is in better shape to suffer this kind of loss than any team in the country. Trent is fantastic. We will get a real demonstration of what Eddie Lacy brings to the table (and when the game is not yet put away). Expectations for him are very high, also. Goode is a very capable back, of course. Bama won't be exactly what we were at RB, but we should be just fine.
The game against SJSU just got a bit more intriguing.
Roll Tide!
