I don't think it'll be that many teams, which will limit the ability for it to really be minor leagues. How many money teams are left that are not in the SEC or Big 10? Clemson, UNC, Florida State, and UVA are considered locks. Miami, Oregon, and Washington are considered on the bubble. How many money teams exist in the SEC and Big 10? Now move the goalposts from entry to those to entry into this new league. If you take only the most valuable those bubble teams fall off the bubble. The Big 10 its Ohio State, Michigan, Penn State, USC for sure. SEC its Alabama, Florida, Georgia, Texas, Oklahoma, and LSU for sure. Clemson, Florida State, and UNC join. For arguements sake throw in Notre Dame too for a clear 12. Michigan State, Wisconsin, Texas A&M can come with for rivalries sake and then add Oregon and Washington to cover more coast to coast. There's your 16 elite teams. Who's the 17th who adds value to that conference? If we're cutting Rutgers and Maryland we're not bringing with anyone else who doesn't add value, that defeats the purpose for those teams to break away and join their own thing in the first place.
My point is that money will win out every single time. If Alabama wants to share money they'll just stay in the SEC. if they get tired of Ole Miss getting money they can call up the rest of the big value teams and go on their own. I dont think theres enough money schools to get the Big 10 and SEC to 24 each now
