With Stanford's loss to USC, the race to the national title is now between four undefeated teams: Alabama, Florida State, Ohio State and Baylor.
All four teams will likely face at least one if not two ranked opponents before the bowl season. So there's plenty of football left to be played.
Alabama has Auburn and an SEC title game should they beat the Tigers. Florida State has the ACC title game. Ohio State has the Big Ten title game, and Baylor has Oklahoma State this week.
Again, there's plenty of season left to be played, and losses suffered by any of these teams could settle all the debates. But if four BCS conference teams finish undefeated, it's going to be hard to tell two of them that they can't play for a national title.
The playoff system, which goes in next season, can't come fast enough.
