SCOTUS says no entity can limit how much the players are paid. Thus the divisional limits cannot be based on some pay scale.
Since all 3 divisions are mentioned, remember what D III is. It is a "no scholarship" true amateur deal the NCAA funds the administration of out of its profits. As the NCAA is becoming totally irrelevant, these schools will be told to figure it out on their own.
Then we have D II. The main difference in D II and the NAIA is not level of competition, it is that D II funds travel and expenses for championships, and the NAIA doesn't. Again, I think the D II schools will be told to figure it out on their own.
Which brings us the DI. Now we have three parts to consider here.
First is football. As to I-A (or FBS) the NCAA no longer matters. It is being run by the Walt Disney Company. Now can they really make a smaller "super programs" deal? That is a question for lawyers and courts. Sounds a lot like collusion in restraint of trade, doesn't it? As to I-AA (or FCS), unlike in our time where we lost money by advancing in the playoffs, the NCAA funds the deal out of the basketball $$. Do we really NEED an in-between division, a "I-Aa" ? Really? So there is an ESPN mega schools champion out of 50 schools; then a not quite that champion out of the remining 70; then a not quite that out of the 90 or so in I-AA, and the a D II champion. Sounds like everybody gets a trophy and an orange slice to me. So if the top 50 are out, everybody else is I-AA.
Second is basketball. The NCAA pays for EVERYTHING via basketball. It does not what to see what happened to football happen to basketball, but I don't think it can be helped.
Then there is everything else. Again, paid for by basketball profits. Won't be anymore. The NCAA will rent a venue and buy some trophies, but that is all. Figure out your own hotels and transportation on your own.
