Several people in here have delusional ideas as to what they think is going to happen. When in short it's very simple. Given the ranking of Auburn, Georgia and Alabama, the SEC Champion is going to be in the playoff. Guaranteed. Even if it is 2 loss Auburn. The committee has already shown their hand on this by putting them at #6. If by some unlikely miracle Auburn wins out, they would have to put them in. Bama may still get in, depending on how Wisconsin finishes. If Bama were to lose the IB, they would need Wisconsin AND Clemson to lose to get in. Miami or Clemson will be eliminated when they play.

That leaves these options to take the final 4 spots (assuming OU and Wisconsin win out):
SEC Champ
MIAMI/CLEMSON
OU
WISCONSIN

For the record, there's no way I see Wisconsin getting out undefeated. In fact, it's likely Michigan beats them this weekend.
