Agreed. SEC would possibly respond by adding more schools, but what schools are out there if you take away the B1G, ACC and PAC-12 besides BIG12 leftovers? Nothing that adds enough value to compete with the scheduling and voting power of the three remaining P5 conferences, IMO. Frankly outside of adding Okie St. or WVU, anyone else dilutes both the product and the cut of the pie each school gets from ESPN.
A scheduling alliance with the B1G and PAC-12 may enable the ACC to bring ESPN back to the table to re-negotiate its horrible media rights deal.
OR...let ESPN, FOX, CBS, NBC and streaming services bid against each other for exclusive rights to these new inter-conference games. While ESPN is broadcasting the Iron Bowl or Texas/OU on prime time, CBS/FOX/NBC could counter with Miami/USC, Clemson/Taint, Oregon/Michigan, FSU/State Penn etc. Exciting, bowl-season type match-ups with playoff implications every week. Imagine if you could somehow convince the Domers to jump on board too. They could stay independent and help drive up the price. That package would be worth stupid money (split 42 ways mind you, but it would supplement the conference's current TV deals).
Interesting to see where this goes, hopefully straight up the SEC's ***.
