I could be wrong on some of the details so correct me in I'm wrong, but my understanding of all this is that revenue sharing for student athletes will begin in the next academic year. Each school will pay out a cap the first year of $20.5 million. Most of that will go to football players. Men's basketball will probably be the second highest budgeted team. It is up to the schools to determine what each team gets.
On top of that there will be NIL but it will be heavily regulated by the NCAA. It won't be the pay for play model that currently exists where someone like AJ Dybantsa can get $5 million just for playing at BYU. Each student athlete can get their own NIL deals but the NCAA will determine what "market" is for promoting a product. How will they determine this? No idea! This seems to spell the end of the collectives since those have funded the pay for play model that currently exists.
Everything is still up in the air and the implementation of all this has not been approved yet. Sounds like a pandora's box of issues coming but we are in unchartered waters now.
This kind of explains it.
