IMO, that is the wrong conference to focus on - IMHO, it is the SEC folks should be watching. They want to expand the markets they play in - hence, no desire for Clemson or FSU - and many speculate UNC and Va Tech are very high on their radar. If that happens, that takes them to 16, and they are done. If they do, it also opens up the door for more chaos -
does Pac12 make a move - it has to go after OK or TX schools or sit still, forever (absent the compelling UNR, Boise, SDSU moves they have alredy laughed over).
how does B12 react?
What does B10 do - they love Texas, they want Virginia and, to a lesser extent, Ga Tech. 2 more gets them to 16, and they are done.
In other words, the B10 move made further conference moves more likely, not less. I am in the camp of thinking ACC will not move fast to expand and will make moves designed to keep the schools most at risk of leaving happy. Swofford made several good moves over the last decade, and then made a horrible move by creating a schism in the conference for no good reason.
