I'd be pretty surprised if Ohio State doesn't blow Miami out. Think Indiana will win but expect a relatively close game.
Ole Miss gets a relatively easy 1st game without Kiffin even with it being the 2nd game between them (see OU/Bama for what can happen in game 2 in a year). Tulane is just not on the level of top-tier teams.
As I said in my predictions, Oregon might have the biggest playoff win ever. Still expect a demolition in that one.
