I've got no insight other than what I've read online (and I've read a lot online about this), but it seems clear that one way or another, Florida State is gonzo. FSU is the #1 TV audience draw in the ACC; Clemson does well against other marquee opponents but doesn't really move the needle on their own (e.g. Clemson vs. Boston College, Wake FOrest, etc.), so their departure REALLY hurts the ACC conference viewership #'s. And as prestigious as some of their schools are academically, their athletic media numbers are pedestrian at best. In other words, their current contract payouts seem proportional when taken collectively as a conference.
All this comes at a time when it appears (allegedly) that their former commissioner John Swofford signed one GOR extension unilaterally w/o having that GOR extension ratified by the conference members. It's somewhat murky whether he had the authority to do so, depending on who you listen to. Part B of this madness is there appears to be (allegedly) an ESPN ONLY option to extend the current GOR agreement ending in 2026 out to 2034, but ESPN has not yet signed that extension. That's kind of good news if you're a FSU fan as it appears damages may be (allegedly) paid out through the current contract period ... which they're also contesting.
I suspect the conference will go the way of the PAC12 as the B1G and SEC are waiting in the wings to snap up the large brands and the smaller ones are simply going to hit the ground. It sucks for those smaller schools, but their media numbers just simply don't move the needle for the networks or their advertisers. They may survive as a BIG12 level conference, with the remaining schools and orphans from the PAC12 (Stanford, Cal + SMU), but if/when FSU leaves ... the rest of those cats are going to be scrambling to get the best deal that they can for their own institutions, brotherhood be damned.
My $0.02 worth on it.
