They obviously get a bye, but then their first game would be a neutral site bowl game.
Under the proposal for a 12-team format, the four highest-ranked conference champions would be seeded 1-4 and receive a first-round bye. Teams 5-12 would play each other in the first round on the home field of the higher-ranked team. The quarterfinals and semifinals would be played in bowl games, and the national championship game would remain at a neutral site.
