I think this all ends with a breakaway and compensation structure anyway. Governance and athlete comp are bigger issues than TV as far as ramifications go and I don't think they loom long on the horizon. I don't see the ACC lasting since there's almost no backfill programs to choose from that would add quality to the league (maybe SMU and Tulane? Yikes)
Hopefully - SEC, Big 12, Big 10 merge to comprise 48 teams with 8 6-team pods. Play each opponent in your pod (5), (4) games outside your pod, and (3) buy games/G5 games. This number would be seamlessly incorporated into the playoff (8 champs, 4 wild cards). We'd probably get Cockeye, ISU, Kansas, K State, Mizzou, and Minnesota/Illinois. Fun!
More likely - Big Ten and SEC merge in this structure. Would have more parity and governance, as well as higher payouts per school. Probably better connections with the NFL. Probably 40 teams, 8 divisions of 5. I think you'd get more interesting schedules this way but we'd be closer to the bottom of the pecking order. We'd probably get Cockeye, Mizzou, Minnesota, Wisconsin. Also fun but less! Big Ten/SEC schools are the real revenue drivers and decision-makers, so they'd probably be more in favor of this. Northwestern-Alabama is probably a closer financial gap to close than Cincinnati-Alabama in terms of support and setting a 'salary cap'.
Possible and shitty - Ohio State, Penn State, Michigan, Clemson, Florida State, Notre Dame, and USC join the SEC or some of its members in a superleague. I think in this scenario the payouts per school could be so high that it wouldn't be cost-inhibitive for them to suffer the consequences of splitting. Until there's real, strong governance in college football and/or the compensation issue is truly settled there's a non-zero chance this takes place. With a smaller number of member schools, there's a stronger likelihood this gets destroyed by university regents nationwide.
