Yes, it's clearly a fools errand, but interesting.Totally fair but in that case if clemson and lets say FSU were to leave in 2036 they would most likely try to add 2 more schools. At this point close to half the conference wouldn't have a landing spot kinda like the big 12 which is why the big 12 added and didn't disband. Now in 2036 all bets are off and who knows what will happen then but speculating on something 14 years in the future is a fools errand.
As I understand the BIG XII rules, we could have disbanded if 8 of 10 voted to do so. The fear was being the 2 teams that didn't have a landing place. Using you're scenario, If Clemson & FSU agreed to go to the Sec in 2036 (assuming they have the same 75% rule) if 9 of the 12 remaining had invites, wouldn't they just say screw it and pull the plug? (or perhaps I should say drown the 3)
Again, I don't know what happens to GOR if the ACC disbands.
