Colorado has been in substantive talks with the Big 12 about possibly joining the growing league, a source with knowledge of the discussions tells CBS Sports.
While a move out of the Pac-12 is not assured, Colorado is performing due diligence to determine whether to return to the conference it once called home. The Buffaloes, like the rest of the Pac-12, remain in wait-and-see mode regarding a new media rights deal that has yet to be solidified.
Colorado and the Big 12 have met face-to-face while involved in consistent talks over a period several months, according to multiple sources. It was made clear that a move to the Big 12 would not be made without the support of football coach Deion Sanders.
