I don’t think that’s how it will ever play out. There’s always going to be kids out there the biggies miss on out of high school. Or from overseas. Or, kids who don’t work out at bigger schools. And, some of the big schools have mediocre coaches. A good coach will maximize talent and win with their team. Even if it’s rebuilt every year.
Ps, IMO, the thing that ends the NIL money escalation = bad economy. If people get financially pinched, they will not donate as if it comes down to taking a holiday trip, versus paying for a kid to get their Alma mater more wins, they are prolly gonna pick the trip every time.
