The Big 12 is "involved in deep discussions" about adding Pac-12 teams, according to Dennis Dodd of CBS Sports.
The Big 12 reportedly wants to add at least four teams and is targeting Arizona, Arizona State, Colorado and Utah. Oregon and Washington are also in the mix to join and make the Big 12 an 18-team conference, per Dodd.
"Everything is on the table," a Big 12 source told Dodd.
Last week, USC and UCLA left the Pac-12 for the Big Ten, where they are set to begin play in 2024.
