“Arizona, Arizona State, Colorado and Utah bring an annual average value (AAV) that at least matches the 12 members of the Big 12 set to remain with the league once Texas and Oklahoma leave in 2025.
That is one reason why Big 12 expansion would work in this case as the conference would not aim to make its slices of media rights pie smaller. It's not yet known whether adding Oregon and Washington is viewed the same way by the Big 12”
The point being all theses teams have value. If UW and OU stay a merger benefits a few Big 12 teams more than adding a few pac 12 teams
