While I'd prefer they go West, grabbing the best of the AAC West (Cincy, UCF, Memphis, and Houston) seems like a strong move that will improve the Big 12 and would aid in long term stability (smaller East and West conferences than something that stretches from Florida to Idaho).
Granted, I think taking San Diego, BYU, Boise and one more (Air Force or Houston?) would be a great choice — maybe even if they can get WVU to leave and one more western team.
