Yeah, doesn't hurt to ask but also, never gonna happen (ND to B12). I think certainly there's a high probability of some movement between the Pac12 and Big12. The question for me is, which of those two conferences is in a better position? I think if Wahington and Oregon leave then yeah, that's easy the B12 is better off and likely to absorb some of the Pac12.If I'm Washington, Oregon, Wazzu, Colorado, Utah, or Oregon State, I'm also calling the Big 12 to gauge their interest. Some of those schools will not end up in the B1G or the SEC. Colorado and Utah make so much sense for the Big 12 geographically.
If you want to get really nuts, if I'm the Big 12 commissioner I really screw with things and I call ND and invite them to join the Big 12. Makes no sense for ND to leave all of their traditional opponents, but if I'm the Big 12 commissioner I think it wouldn't hurt to ask, and it might make the B1G or SEC sweat for about five minutes.
But is it possible the Pac12 can convince some B12 teams to come over on the condition those two to stay, and then convince those two to stay with that expansion and then also maybe offer them a larger cut of the tv deal than the other programs? (For context, Pac12 used to give UCLA and USC a larger cut but then a few years ago changed to giving programs equal shares, which as I understand it was the origin of those two schools' dissatisfaction with the conference). If I'm running the Pac12, I think I give that a shot. It's a long shot but you gotta do something.
