I'd love to go back to the regionalism of yesteryear as much as anyone but that ship has frankly sailed with the amount of TV and NIL money in the sport. Money is the number one factor at the administrative level as well as for the talent on the field. There is no going back.
What I hope we get to is the top however many schools forming their own NFL lite super league and competing in a separate division, essentially autonomous from the NCAA or at least governed with their own set of rules, and we can get back to sensible conferences for the rest of the sport. As dumb as it is that Washington, Oregon, USC, and UCLA will be playing conference football games against Penn State, Rutgers, Maryland, and Ohio State; Cal and Stanford will be playing conference football games against Syracuse and Georgia Tech; and Utah, Arizona, and Arizona State are playing UCF and West Virginia... it is orders of magnitude dumber that those are now conference games in more schedule/travel intensive non revenue sports.
It's one thing to acknowledge, implicitly or explicitly, that football is purely about money now, but the latest round of realignment will really fuck with non-revenue sports where athletes are actually students. Let the cash cow that is football fund a good experience for students, alumni, and fans of the rest of college athletics.
