Before the College Football Playoff field is set, there is one last chance to make a case to the selection committee.

No. 5 Oklahoma and No. 6 Ohio State both need to win Saturday — and they should both be rooting for Alabama.

The Sooners enter Championship Saturday with a chance to make the playoff for a second straight season. Oklahoma faces archrival Texas for the Big 12 title in the first of four Power Five championship games that will decide the four-team playoff field that will be revealed Sunday.

Ohio State plays Northwestern in the Big Ten championship. No. 1 Alabama faces No. 4 Georgia for the SEC title and a win by the Crimson Tide could open the door for the Sooners or Buckeyes. No. 2 Clemson is heavily favored against Pittsburgh in the ACC championship game.

In all, there are nine championship games on Saturday: Besides the SEC, ACC, Big Ten and Big 12 games, titles will be settled in the Sun Belt (Louisiana-Lafayette at Appalachian State), Conference USA (UAB at Middle Tennessee), American Athletic (Memphis at UCF), the SWAC (Southern at Alcorn State) and the Mountain West (Fresno State at Boise State).
