At some point, it makes sense for Big12 & ACC to join. But before it happens schools like: ND, Miami, FSU, UNC, UVA, KU, Utah, ASU, etc will be in the Big10 or SEC. Big12/ACC teams will be screaming "Pick Me, I'll take a partial share for the next 30 years!!"Cleanest would be ACC/B12 merger and create 3 new 11-team conferences. ACC GOR buyout drastically decreases at the same time the current B12 deal expires so strike a deal with ESPN, pool rights and engage CBS/Paramount/TNT and/or Amazon for the following 3 conferences (if B10/Fox and ESPN/SEC won't play ball on 7x10):
ACC: NC State, UNC, Duke, Wake, Virginia, VA Tech, Clemson, Florida St, GA Tech, Miami FL, UCF
Big 12 (old SWC & Big East): TCU, Texas Tech, Baylor, SMU, Houston, West Virginia, Syracuse, BC, Louisville, Pitt, Cincinnati
Big Country (PAC and Big 8): Arizona, Arizona St, Utah, BYU, Stanford, Cal, Colorado, KU, KSU, ISU, OK St
Schedule smartly so that CBS has an attractive GOTW each week from the 3 conferences including non con matchups between the 3. TNT and/or ESPN gets the next best games with the rest on CBSSN, Paramount+ and/or Amazon. You have inventory running from 10 AM CT through 9 PM CT. Play 10 game conference schedules with 3 champs getting CFP AQ.
No way any federal legislation is going to be able to prevent further realignment. Supreme Court would strike it down. Or it would just result in earlier realignment.
