A plan to expand the College Football Playoff stalled Wednesday when a key committee was unable to reach consensus on whether to grow the postseason format from four to 12 teams.

The 10 major college conference commissioners and Notre Dame’s athletic director who make up the management committee met to share feedback from their members and address concerns about the expansion proposal that was unveiled in June.

“As the committee moves forward, there remains issues to be discussed,” CFP Executive Director Bill Hancock said in a statement. “Given the complexity of these matters, the management committee will meet again in Chicago next week to continue our discussions.”

The meeting in the Dallas area, which was attended in person by some of the participants and virtually by others, was a prelude to the Chicago session that was supposed to include the CFP board of managers.

The board is comprised of university presidents and chancellors representing each conference. The board has final say in all matters related to the playoff and there was hope the management committee would bring the presidents a recommendation to approve a format change.

Instead, the management committee will reconvene next week, with the presidents joining via Zoom. No vote is expected.

Since the public rollout of the 12-team playoff plan, there have been concerns raised about components of the format, including the possibility of increasing the number of games in a season required to play for a championship to as much as 17. There were also concerns about the impact subsequent conference realignment could have on a new version of the CFP.

In July, the Southeastern Conference invited Texas and Oklahoma to leave the Big 12 and join the powerhouse league in 2025 after the Big 12’s current television contracts expire.
