This is a hard one for me to call. Seriously. I know aTm struggled mightily with Arkansas, but I happen to think the Aggies were already beat down from their schedule at that point. They've had a week to recover. So has Alabama, but I don't think we get anyone back on defense that was supposed to be available this year anyway, and the offense is in good shape.
I don't want to predict a let down here, but I don't think Bama covers (18.5 at the time of this writing): Tide 46 Aggies 31.
