So reworded, your point is something like this, I think:
"once the Supreme Court sets the precedent that (associations of) schools can't put restrictions on student-athletes, then the athletes suddenly now have unlimited power to demand anything they want from the schools".
I see your point. I just don't think it's going to be as black-and-white as maybe the above is making it out to be.
Athletes want, and probably deserve in P5 football and men's basketball, some amount more. Maybe they should receive like a "double scholarship worth" from the school, and then whatever they can get for themselves in bona fide endorsement deals. The schools/conferences won't have to fork over that part, themselves.
The crucial difficulty is to make sure these endorsement deals are not just BS, some rich boosters saying they're giving a "deal" to a player, but it's a straight up wad of cash in a bag for little or no work or any actual endorsing.
But at the end of the day, they don't want to kill the golden goose. They want it to keep going. They just want a bit more.
