IF Tennessee wins out the Cotton Bowl could take us, and unless Nebraska upsets Texas in the Big 12 Champ. Game, then Oklahoma would go to the Cotton.
There are some people around the program that think the Cotton could take Tennessee. I'm not 100% sure. I'm not sure how LSU fits into that picture. If they beat Ole Miss and Arkansas, and make an at-large BCS spot with two losses, I think Tennessee could go, but if they don't go BCS, I'm not sure the Cotton would pass a 2-loss LSU up. If they lose to Arkansas and end up with three losses, I think there is a chance the Cotton takes us over them, but it's no given.
Anyway....if we do go to the Cotton and play Oklahoma, with Peterson coming back for the bowl game........well, I'm an optimist, but let's just say I would be worried.
