There are four at-large bids in the BCS process, but the Alabama Crimson Tide and Oklahoma Sooners are all locks to take two of the spots.
Even if Oklahoma were to lose to the Cowboys, they still would likely play in the Fiesta Bowl. Alabama is locked into the Sugar Bowl if they were to win their next two games.
So, the biggest question is to who those two teams play? The Fiesta Bowl gets the first selection which is followed up by the Sugar Bowl.
There are, however, a few teams that nobody is talking about which actually have a decent chance into making a BCS bowl.
