The only answer to this is:
- 1 time transfer, no/rare waivers. Grad students can transfer once.
- Direct payment with a CBA with a player association. Not sure how the payment goes ... does each team have a limit? Do all QBs get $X, then OL get $X? Do all players get the same ... say, $30,000 per year with the rest made up with NIL.
- NIL - you can't cap it, but you can have reporting requirements through the CBA, and from the schools.
- Strict rules on college/collective provision of NIL, with an investigative body that has teeth and will do its job. Once the players are getting paid, and the CBA exists the NCAA shouldn't have a problem enforcing things.
The last part is the tricky part ... mostly because all the states are passing their own NIL laws. The hope here is that once you pay the players directly, and they have a CBA, the states will back off or the feds will pass a federal law. Right now neither care to do so because they are looking after the players, or so they say, and the schools are seen as the bad guys. Once the players are paid and represented, then NIL laws won't be as important.
