I'm with McPeachy. Now that the separation is almost complete and there isn't anything but egos separating the G5, conference affiliation doesn't mean much. Hell, I'd take something like: WYO, CSU, AF, UNM, UTEP and 3 of any of these: USU, BSU, maybe NMSU (yes I know, but geography and rivalry with UNM and UTEP), UTSA, maybe UNT, or ??? Bball would take a big hit, though.
I guess I'm just not smart enough to understand, but entertainment money (i.e. TV) was/is driving the bus. Teams joining the P5 makes financial sense for the teams stepping up and I would assume the P5 if they make that decision.
For every remaining scenario in the G5, I don't see any realignment that would be financially beneficial. The P5 isn't going to let another conference in. I think byu and even the MWC are going to take significant hits on TV contracts the next time around. The AAC only has cash because of buyouts but those aren't long-term. I get the argument about being the strongest conference for the NY6 bid, but hell that isn't a guarantee. It might even hurt the chances.
I guess I'm just dense, because I can't see the money trail that would drive any realignment in the G5 ranks. If anything, I think some teams may decide to scale back athletics which could drive some rearrangement I suppose.
