This is just talk. All of those schools are under contract including the new adds until 2036. That's why FSU and Clemson are still there. They signed the grant of rights and are obligated until then. If they leave whatever money they get from either the Big 10 or SEC would go to the ACC.
Big difference between keeping revenue schools and kicking out leeches. GOR doesn't apply in the latter. I would imagine some kind of compensation would be due those schools, removed, for their shares in the conference, however, it won't help SMU, Cal, and Stanford. Cal and Stanford would be better off shoring up the MWC merger with Wash St and Oregon St and probably preventing Air Force from wanting to join the new proposed league and just staying put. That cross-country travel isn't justified at G5 or slightly better TV money.
