Huge losers are Oregon and Notre Dame.
Oregon may be stuck in what's essentially a "Group of 5" conference of B12/P12 leftovers.
ND always had enough viewership clout to flirt with the B1G but stay at arms length. Now the B1G can, and probably will, tell ND they aren't interested anymore. ND is then stuck with the "also ran ACC" which the SEC will gut eventually but I doubt the SEC wants or needs ND either.
I'm also hearing rumbles the B1G might want NC or UVa and Duke, as they're academic (AAU) fits for the B1G and as a preemptive strike to weaken the ACC even more.
If the ACC caves before 2035, waives the big money payouts then the SEC poaches Miami and FSU, for sure, and maybe a couple of others.
I'd say within a few years the SEC and B1G build a pro league, totally ditch the last bit of the "student athlete" BS, and align with the NFL in some way.
