Most years, not even the National champ gets a lot of credit going into the next year(depending on who they lose), but you win 3 out of 4 and you build up a lot of good will with the voters, at that point you get the benefit of the doubt that you're damn good until proven otherwise.
Stanford did do Ohio St a big favor tonight, but Baylor still has a very good chance of jumping Ohio St in the BCS if Baylor wins the next couple weeks. They play 3 straight ranked teams starting with tonight.
If everyone wins out that is undefeated now, it ends up 1. Alabama 2. Fla St 3. Baylor 4. Ohio St
