Michigan or Texas should win it all!!
I’ll say Alabama since they ended the season on a good note but it’s just hard to tell with all the time off which teams will come out hot and which teams will be flat.
I still have faith in the adage that "Championships are won with defense and the running game" which are Michigan strengths. Those are also aspects of the game which are more instinctive than anything else, so I think that'll be slowed less by the time off mentioned by @Darin.
