College Football Playoff expansion looked like an inevitability not long ago, and that may still be the case. However, the chances of it being implemented quickly appear to be dwindling.

Pete Thamel of Yahoo Sports reported Friday that the chances of a quick expansion to the playoff format appear to be shrinking, largely because of Texas and Oklahoma’s pending move to the SEC and the subsequent destabilization of the Big 12. That has made the environment more uncertain, and has also fueled skepticism around the power that both the SEC and ESPN already hold.

Ohio State athletic director Gene Smith, one of the most powerful and influential athletic directors in the nation, suggested that “the pause button should be hit” on playoff expansion talks while “legitimate concerns” linger about the college football landscape.
