ACC officials discussing the possibility of adding Cal, Stanford

There are several obvious hurdles to the ACC absorbing Pac-12 schools including travel, revenue sharing and scheduling/television rights deals as most of the ACC member schools are located on the east coast and the remaining Pac-12 schools on the west coast.

"It's complicated," an anonymous ACC source told CBS Sports. "There's a significant travel expense. I think it's going to be all over the board with both the ADs and the presidents in what they may want to do. [Cal and Stanford] would likely have to take a reduced share. Eventually, though, they're going to want to become a full share."

After Oregon and Washington left to join the Big Ten, and Arizona, Arizona State, Colorado and Utah departing for the Big 12, the Pac-12 is down to just four schools — Cal, Oregon State, Stanford and Washington State.

There is a possibility the Pac-12 could merge with the Mountain West to get over the NCAA-mandated limit of six members for football. Beginning with the 2024-25 season, the ACC will have 14 football schools, the Big Ten will have 18 and the Big 12 and SEC will both have 16.

If Cal and Stanford bolt for the ACC, Oregon State and Washington State could join either the Mountain West or American Athletic Conference.
