NIL and Revenue Sharing are wrongly getting lumped into one big thing and called NIL.
UK can direct a player, toward possible NIL possibilitys. They have very little say over it. I think the state, says it can't be Alcohol, Tabocoo or Gambling. Starting this year.... All NIL deal over $600 has to be entered into a software program called NIL Go. And be vetted to see if the NIL deal is fair market value, and not some business giving 2 million for a 10 second commercial. Word is NIL go, is extreamly slow, as the Ncaa only has 4 people working in this department. The payments for NIL are made between the player, agent and business... They could structure it to be paid over time. But from my understanding.. NIL can not be tied to performance... It's strictly for there Name, I age or Likeness.
Revenue Share is a whole other animal. It can be set up like a normal business contract. With a base pay, and then incentives for games played, performance and a buyout if they transfer mid season. They can be structured to be paid over time and so forth... The university has a huge laditude to do as they see fit, just like any other business contract. Which is why having a GM is becoming a more attractive position for schools to have.
