Ordinarily, I'd say Tennessee. However, as long as Fulmer is there it's awfully difficult to hope UT wins any game, regardless of the opponent. I didn't like Fulmer even before the NCAA mess and even before UT started beating Bama in the recent streak. And UT is really no better than ND, as far as hometown boys: less than 1/3 of the players on the UT roster are actually from the state of Tennessee while Bama's roster is about 70% Alabama boys.
I agree with wastedmason, even if UT wins out it won't help Bama in the BCS. USC and Texas are preordained national championship contenders and a loss by either may not even be enough to prevent it. First, I don't see Texas losing to anybody, though it would be funny to see aTm beat them. Second, even if USC loses to UCLA, they'd probably only drop to #2 and Texas would move up to #1. UCLA would possibly leapfrog Bama and be the #1 team.
I guess I'll just hope they both lose somehow.
