It should be auto bids for P5 conference champions, 1 auto bid for the highest non-P5 conference champion and 2 at-large bids to the highest ranked teams, per average based on AP, Coaches and Sagarin rankings, that are not conference champions.

Alabama
Stanford
Michigan St
Oklahoma
Clemson
Houston
Florida State
Ohio State
