College athletics are going to look very different in the coming years, and new NCAA Big 12 commissioner Brett Yormark is well aware.

At Big 12 Media Days, Yormark was asked about potentially adding teams from the Pac-12 conference, two weeks after USC and UCLA announced their move to the Big Ten conference in 2024.

"As I said in my opening comments, we’re exploring all options," Yormark said on Wednesday. "And we’re open for business. And optionality is good, and we’re vetting all of them. I think it's fair to say I've received a lot of phone calls, a lot of interest. We're exploring those levels of interest. Nothing is imminent."
