I don't know if this question has been asked, but what if there are 3 undefeated teams at seasons end? Who plays in the championship game. It's not inconceivable that Oregon, Auburn and Michigan State could be undefeated. In all likelihood, based on the current polls, Michigan State would probably be on the outside looking in. Oh and then there's the Boise State and TCU who might have something to say as well. The plus one model has been mentioned as a possible solution but once again in a worst case scenario where you have possibly the top 5 in the BCS undefeated, there's still going to be someone getting passed over.
