Since this is all about TV money and the program start time is now dictated by the networks and Apple and Amazon want in to the network sweepstakes, the answer is to say Fuck You to the EsPN and Fox nightmare stranglehold and create a new exclusive Super Conference League which contains the remnants of the ACC, Pac10, the Big12 and the remaining attractive independent teams.
The caveat being that in order to be a league member the league requires that you sign the agreement that you can only schedule amoung the league participants thereby shutting out crossover games between the Big10 and the SEC... this isolates those two leagues from a future scheduling standpoint and guarantees the remaining relevance of the newly created Super League from a future TV contract standpoint and boosts the probability of a seat at the future playoffs because the accomplished fait of the playoffs then moves to a 6-8 team alignment for sure in order to maintain interest in the sport.
The kicker long term is that the league alliance at the administrative rules level refuses to make TV deals that force conference participants to schedule more than 20% of home games outside of the 12-4 timeslot thereby restoring the value of the homefield ticket for local citizens. The other kicker longer term is that the alliance will offer the attraction of interesting crossover games because league participants will be limited to the scheduling choice of league participants ~ no ABC with the drek mid major or Portland State level gimmie games.
From my perspective, the above is the solution to guarantee future relevance to the remaining leagues ~ the alternative is a slow death scenario, which may be the longer term outcome for the sport anyway in light of the NIL progression anyway. The only way this will work is if league participants agree to sign super long term deals of a decade or more with poison pill truly giant stop sign exit fees if they leave to prevent the otherwise inevitable poaching that will occur from the Fox / ESPN death squads.
