Alabama/LSU are interchangeable at this point right?

So Auburn would need to go get at least 1 win vs those two teams to create some separation there.

Otherwise I could see the loser of ALA/LSU sneaking their way into that 4th place slot, particularly if it is close.

Every year I keep thinking it will be another one where there will be multiple undefeated teams to the point that it is harder to determine the playoff (or BCS) scenarios and rarely does that happen, however I don't think it is impossible for there to be 4 of the P5 to have an undefeated team. I think the most likely scenario is Clemson and/or Oklahoma going undefeated (they have the easier roads) and the SEC and Big Can't count to have champions with a single loss.
