OUt of the teams that have one loss left?
Michigan (obviously), USC and Arkansas would give them the most trouble I think.
I still think Arkansas would need a lot of things to break their way to make it to the Nat'l Title game. First, they've got LSU on Friday, and the Tigers will definitely want to prove that last night was a fluke. Then they have to get past Florida. Neither one is a gimme, they'll have to win both convincigly to get the style points. Then they have to hope the computers and pollsters forget about that blowout USC handed them at home in September. They're in the same situation Notre Dame is. The pollsters won't drop Michigan below number 4 this week, IMO.
