I'm of the same mind. ESPN won't allow an ACC team to be taken and holds the cards (bidding on the B1G contract) to get its way.
That means UConn is the only available east coast property.
Texas is also in the ESPN orbit and won't be available. That leaves Oklahoma and Kansas as the only attractive properties available. Of those three, the ranking is probably Oklahoma and UConn ahead of Kansas, though Kansas is deserving too.
Oklahoma State is probably attractive enough to get an SEC bid if the B12 breaks up, so I don't think the sister would be a major issue. But, if in order to escape the B12 GoR you had to assemble a critical mass of B12 teams, I could see Oklahoma and Kansas going together to the B1G.
