Vegas: Auburn-3
Clemson -7 1/2
UCF -7
Ohio State -51/2
Okla -6 1/2

This weeks playoff ratings will be interesting given the combinations of outcomes. There has never been a two loss team in playoff (Not good history for Auburn) Bama is highest rated team and like OSU last year could leapfrog Auburn even if they win. GA will have home field advantage this time .
