IMHO,
- Ivy League schools have a perception (not completely true) and they don't need athletics.
- Below that, in the vast competition for the rich and upper middle class, spoiled rich kid among the 1000s of private (and quasi-private like WVU) schools, each school puts forward a package of lifestyle, and kids get rich daddy (or you and me taxpayer) to send them where they fit in. For some kids, sports at a high level, is part of what they want their school experience (and their life thereafter as they gently razz Buffy and Chippy about how "their" Blue Devils are doing) to be. For others, other things are important.
- NIL is going to peak and crash. Blunt fact is that not that many people give a damn about college sports other than men's basketball and football. Hockey and baseball in a few places. Maybe men's soccer, but not really. Eventually boosters are going to realize that they are getting no return on their investments and move on.
- Which leaves the big sports at the big schools. In a race about money, my money is on the people with money. There are more rich boosters in places like Miami or LA, than in the whole SEC.
