For now there are no NIL rules and may not be any unless Congress gets involved, which I doubt they would. I think Southern schools would pressure their congressmen to avoid any involvement that would put rules in place.

The notion of amateurism has long been a bedrock principle of the NCAA, but Judge Clifton L. Corker said that a lawsuit filed by attorneys general in Tennessee and Virginia had enough merit to stop the leaders of college sports from imposing any restrictions on prospects signing name, image and likeness (NIL) deals before joining programs. The court order is applicable to all athletes in all states and is effective immediately.

The injunction is not a final ruling in the case, but the judge’s decision is all but certain to open the floodgates for more recruits to sign NIL deals nationwide without fear of repercussions.
