At this point, it seems like the SEC and Big Ten can just handpick whoever they want. So essentially every Pac-12, ACC, and Big-12 school is a free agent. I guess the question is, when do the Power 2 conferences stop expanding? Some schools are going to diminish your return value. Maybe roughly 20 schools for each conference?
I think the Big 12 is actually much, much more secure than the Pac-12 or ACC. Their bluebloods are already taken. With Oklahoma and Texas out of the picture, I don't think the Big Ten/SEC are necessarily salivating over any of the leftovers in the Big 12. So, most Big 12 are aware they're not likely to get an invite, they're most likely staying intact, and they can now recruit other schools that would fit culturally or geographically, like Arizona/ASU/CU/Utah. But, what happens to the Pac-12 and ACC when their top programs are poached? Oregon, Washington, Stanford, Clemson, FSU, and UNC all have obvious value. Miami, Louisville, Virginia, California, and a few others could be intriguing, as well.
The Pac-12 could be days away from crumbling. ACC is certainly vulnerable, too. Guess it mostly depends on how many schools we lose. Hoping to stay intact, but that probably isn't a likely scenario.
