Two teams from the Big 12 playing for the national championship? Absolutely. Three teams from the Big 12 in the BCS? You bet. Only one team from the SEC? It could happen.
Alabama loses to Auburn, then rebounds to beat Florida in the SEC title game.
Missouri beats Texas Tech in the Big 12 championship game.
That leaves a top four in the BCS that would look like this:
The BCS championship game would be Texas-Oklahoma but a spot would have to be reserved for Missouri, the Big 12 champion. Rules state that only two teams from a conference can go to the BCS bowl. Oops. They would have to make room for three.
Assume that Oregon State wins the Pac-10 and goes to the Rose Bowl. That would guarantee USC a spot as an at-large because it finished in the top four. It also means only one SEC team (Alabama) would be in the BCS.
Florida would be shut out because the at-large spots would go to Utah, USC, Texas and Oklahoma. That's right, two at-large teams would be playing for the national championship!
