For me, it would be Urban Meyer.
Woody. and I was around for everyone of his seasons. He lost about as many big games as he won. Not a knock on Woody, I am a Woody aficionado.
Tressel. HOF coach. Love him. But, for one game, favored or even, I don't think so.
Ryan Day. Too early to tell. He hasn't really done it yet as a head coach. Saturday is his opportunity as a HC.
Urban Meyer. Laser focus on 1 game. Killer instinct. Ability to inspire and focus a team for the biggest game of all. He gets my vote.
