I would completely agree with you if not for the idea that the Big 12 might be asking you to take paycuts in order to join. If the Big 12 allows these new members to become whole in a few years and make the same amount as everyone else, I agree with that entirely. However, if they are planning to use these teams so that a select few can bolt for the Big Ten/Pac-12/SEC/ACC in a few years, it will just make these American schools look like G5 who were 'fortunate' enough to sit at the kids' table for a short time.
I think UConn belongs in the ACC, personally. I think they'd be a great fit for the Big Ten. I see this expansion by the Big 12 as a short term money grab by a select few schools who are going to bolt when the Grant of Rights expires, and these contrived relationships from all over the country won't ever make it seem or feel like a real power conference to the general public. It won't feel like it to me. All the other conferences expanded organically. This won't feel natural IMHO.
