This is all clear as mud, but I don't believe the schools CURRENTLY have anything to do with the NIL contract, that I think is just between the kid and the booster/company. Thus I would say there is 0 to do with academics outside of, hey if you aren't in school at the U or wherever I am not paying you so outside of being eligible I doubt there is anything to that.
Now my idea that there needs to be an actual contract between the school/player/NIL person could change that, but as it sits now I don't think there is anything.
