Realignment has been a hot topic of conversation in college football lately with a lot of moving pieces.

We’re getting more insight as to which pieces might be moving.

Max Olson at The Athletic is reporting four schools — three of which are in the American Athletic Conference — are in the mix to join the Big 12.

Cincinnati, Houston, UCF and BYU are among the schools to be “the most seriously discussed” about joining the Big 12. The news comes after Big 12 athletic directors met with commissioner Bob Bowlsby this week.

Bowlsby released a statement about the meetings Thursday morning, discussing the strength of the conference.

“The eight ADs remain committed to furthering the Big 12 as one of the nation’s premier athletic conferences, and look forward to working with our presidents and chancellors to strengthen the league,” Bowlsby stated. “Future exploration by the group will continue to center on options that best position the long-term strength of the Conference.”

The realignment dominos started to fall when Texas and Oklahoma announced in July that they intend to leave the Big 12 — setting the college football landscape up for a world of change.
