I have normally been against a lot of your views on this stuff, but the recent ruling in favor of direct payment to players for just the P4 schools really pushed me to your side.
If I were the commissioner of the MAC, I'd do what GP1 said and publicly call for a meeting with all G5 ADs but I'd go one step further. I'd invite any Power Conference institution that wants to get back to the more traditional roots of collegiate athletics to join. The sales pitch is a league where they'd be towards the top competitively and would be heroes saving traditional college athletics instead of the villains that power conferences have become.
Once I have an agreement among AD's, take the idea to YouTube, Apple, Netflix, Amazon, etc. Go get exclusive streaming rights money. In the contract, include revenue sharing for the players that comes from the streaming company, not the schools.
Have zero restrictions on NIL potential, but make NIL contractual to promote commitment to the school.
Do not allow any scheduling outside of the league. No "FCS" schools, no schools from the now-semi-pro league. Keep it all in house. Operate the schedule like the NFL with set rotations, no pay days, etc. Play all playoff games on campus with a neutral site championship.
Do this for every sport.
