NIL can still be used by top athletes like a Caitlin Clark to make more money. And NIL will still be used by the big money NIL collectives to lure and buy the really top recruits.
Overall, I agree. The individual big money deals will stick around as long as there are popular athletes. And corporate collectives will stick around so long as the people owning those corporations want to make sure their favorite school wins.
But I think the "fan-base" collectives are probably toast now. I think a key part of the justification for these was "the poor athletes even don't get a share of the revenue, so help them out". Now that the athletes are getting a piece of the pie, people won't want to hand over extra money to these kids who, in many cases, are making more money than them.
