The College football Playoff managing committee says they “reviewed” multiple potential methods of expansion to the CFP this week.

That news came in a release on Friday afternoon that recapped the committee’s annual spring meeting.

CFP Chairman Bill Hancock said the committee still supports the four-team model. However, a “working group” of four members were asked to “consider options for the future.” They shared their findings with the full managing committee this week.

In total, the working group presented 63 potential variations for the playoff. The release says the options included variations with as many as 16 teams.

The committee will review another report on potential expansion at a future meeting, per the release.

“Since January 2019, when the presidents charged us with taking a careful look at all aspects of CFP, including the format, this group has diligently evaluated options for the future,” Hancock said. “Its efforts were delayed as a result of the pandemic, but it met again this week in Dallas, and we look forward to hearing more when its work is complete.

“I want to remind everyone that whatever recommendations the management committee may make, all decisions about our future format—whether to remain at four teams or change to a different format—will be made by the 11 presidents and chancellors who manage the CFP.”

2021 will be the eighth year of the College Football Playoff’s existence. The original agreement was for 12 years, so it’s unlikely the format will be changed before then.

However, this is the first time the College Football Playoff committee has publicly acknowledged the future potential for expansion.
