I haven't seen it talked about here yet but I could see some form of the B-12 remaining in tact after OK and aTm leave. Texas football leaves and the B-12 lets them park their basketball and olympic sports there because with their football gone the other schools have a fighting chance at winning the conference. The B-12 invites the top Mountain West and CUSA teams on the basis that they could retain their BCS bid with schools with high enough winning percentage. The Big-12 allows Texas sports to stay for the same reasons that the Big East puts up with ND. Texas is able to put together a schedule that would help the LHN the most with OK, Texas Tech, aTm, (maybe ND?), etc.
