It's not a question of "how likely" but rather "who is the most likely." I would say evaluating the schedules and who everyone has returning, Clemson is the most likely. As I said in my post, they won't be any worse than they were this year. That doesn't guarantee wins, but they have all the pieces.

I agree that it is hard as hell to go undefeated and win it all, but that's true for every team. Predicting a champion is about relative likelihood.
