USC and UCLA are reportedly planning to leave the Pac-12 for the Big Ten as early as 2024, per Jon Wilner of the Mercury News. However, the Big Ten may not be done expanding.

A source told Brett McMurphy of the Action Network that the Big Ten may not settle at 16 teams after adding UCLA and USC.

In addition, the Big 12 could add Arizona, Arizona State, Utah and Colorado alongside the quartet of recently announced members (BYU, Cincinnati, Houston and UCF) to get to 16 teams as well, per McMurphy.

The Big 12 currently has 10 teams, but Oklahoma and Texas are set to leave for the SEC in July 2025.

Everything is leading toward a superconference era, with The Athletic's Nicole Auerbach, ESPN's Adam Rittenberg and Ross Dellenger of Sports Illustrated noting what could happen next:

The Big Ten and SEC appear to be the top superpowers as of now, with the Big 12 potentially adding a new chunk of teams as well. The big loser here is obviously the Pac-12, which will lose two of its premier names.

Ultimately, the reported USC and UCLA moves are big dominoes that would have ripple effects throughout college football, and now a race to join the new superconferences appears imminent.
