Genetics dude on Twitter is connected in the BIG10, not the SEC.
The SEC is the one that can change all this, when they make their move - and I don't doubt they will make a move. All this talk about the BIG10 moving to 24 to build their national conference. But most of these assumptions are that ESPN will basically just lay down and die, and that the SEC won't protect their region. The BIG10 has their plan for Southeast expansion. But plans change when you get punched in the mouth, and for some reason people expect the SEC to not throw any punches.
SEC could just as easily go for Us, FSU, Clemson, and UNC (ESPN paying an additional like $30-60M/school) by offering us all full shares, then even possibly offer half shares to Virginia schools, GTech,NCSt, etc (which would be ESPN paying basically the same or slightly less than they currently pay those schools) and completely shut the Big10 out of the South East forever. Then ESPN could just drop the rest of the ACC schools. Let them go wherever they want, and tell the Big12 they're (ESPN) not going to pay $20M/school for any further additions since they aren't contractually obligated to do so. I really don't see why that is viewed as an impossible move for the SEC to make, yet it's so likely for the BIG10 to essentially make the same move.
ESPN and Disney aren't broke. And while they did fire hella people, these hosts aren't exactly irreplaceable. Meanwhile CFB actually makes them money.
