My guess is before this 12 team playoff thing gets solidified there's going to be some major realignment amongst the conferences. I would guess the power 5 may become a power 4 with all kinds of mixing and matching going on. Broke up with divisions. So I would pump the brakes on wanting to make any moves if I were OU or UT or anyone else. I think they need to get all these guys in a room and figure this out instead of a couple teams here and a school there just making their own back room deals.
Good point. In the short run it definitely makes sense to ice out programs like all the deadweight in the Big 12. But the problem is that you need cannon fodder to keep the mystique of the big dogs alive. If college football were reduced to the top 20 teams and Oklahoma settled in at being a perennial 6-6 team the allure of the game would wear off really quickly.
