Here is a scenario for you to ponder. Florida beats the Buckeyes by a score of 23/21. A week earlier Michigan stomps the Trojans 45/10 and Boise State routs the Sooners 34/3 leaving Boise State an unbeaten 13/0. Who's number 1 then?
It will be Florida if that scenario pans out.
Michigan might get some AP votes, probably not enough though.
