Things get interesting. Assuming Alabama wins as well, do we jump them?
If Alabama and ND win, who gets that fourth spot? Texas AM is currently ahead of Cincinnati, but it would be odd to take AM who didn't even make their conference championship over Cincinnati. Or do the selection committee throw a curve ball and take them both and leave out Ohio State for their lack of games.
I couldn't see Clemson getting in with 2 losses compared to a couple undefeated and 1 loss teams, but the committee could look at them and say 2 good losses and some good wins are better than no good wins. If ND beats Clemson again in a close one and Clemson gets left out, I can hear the call for an expanded playoff. Which I wouldn't mind, but it wouldn't help them this year.
