Brian Kelly left the Fighting Irish and was introduced as the new coach at LSU on Tuesday, three days after independent Notre Dame finished its season 11-1.

Georgia was first, as it has been for every selection committee ranking so far, and Michigan climbed to No. 2 after it beat last week's No. 2, Ohio State. The Wolverines play Iowa in the Big Ten title game.

Alabama will be third going into the Southeastern Conference championship game with Georgia, and Cincinnati is fourth heading into its American Athletic Conference championship against Houston.

The playoff field will be set Sunday.

The penultimate rankings come the day before the conference commissioners who manage the playoff meet in Dallas for a pivotal gathering.

The management committee — comprised of the commissioners of the 10 FBS conferences and Notre Dame's athletic director — has a self-imposed deadline to agree on how to expand the playoff.

The commissioners have been debating whether to triple the playoff field to 12 teams. For a new model to be in place by the 2024 season, a format would have to be approved by the CFP oversight committee of university presidents and chancellors by mid-January.

If the management committee cannot come to a consensus on the the size of the field at this meeting, it is likely that the soonest expansion could happen would be the 2026 season, after the current television rights contract with ESPN expires.
