I'm not an attorney so I have no idea what the legal aspects of NIL are. That being said, I would think the NCAA or any other volunteer league would have pretty broad latitude to establish the rules under which participants play. Just because Tennessee law makes something legal doesn't mean the NCAA will allow them access to post season play and not disallow their wins if they are playing illegally obtained players. I don't think State law can dictate the NCAA rules of participation. I'm sure it's more complicated than that, but it would surprise me if a State can just pass a law allowing their university to do something and then it becomes something the NCAA has to go along with.
