It could be argued that the B12 would be better off not adding anyone from the PAC, and just standing pat for the time being.
Frankly, the only reason I’d like additional Western teams in the B12 is so BYU is not on an island. For that reason I’d welcome AZ, ASU, and Colorado. But I’m not convinced those 3 would make the conference that much stronger.
Those additions (along with the departure of the LA schools to the B1G) would decimate the PAC, which I would see as a good thing, but that’s just my Law-of-Moses-eye-for-an-eye natural man talking.
