It's funny that you say that. A dozen years ago when Colorado bolted from the B12 (largely to escape from Texas, who was a difficult conference-mate), people said that they would be a better cultural fit in the Pac12 than in a conference with 2 Kansas schools, 2 Oklahoma schools, ISU, TT, and Baylor. I really think that they are still a better cultural fit in the Pac 12 and that this move back to the B12 is purely financial and that the Pac 12's terrible leadership that has brought that about.
I live in Tucson, where the big question right now is "what will the UofA do? The wait for a Pac12 media deal has been excruciatingly long, with no end in sight. Few people here seem to want the UofA to leave the Pac12. The school has more alumni in CA than in any state outside of AZ so a California presence is highly desirable.
