NIL is something that will turn into a salary cap situation...the genie is out of the bottle, so NIL won't go away. However, I could easily see the restriction being a cap, with the penalty being a loss of scholarship for each set dollar amount beyond the cap.
Alternately, we are going to see a lot of schools where they look to drop down to a lesser level of play because they cannot afford to keep up with what the top-10 NIL schools are paying. You would then get something akin to AAA where a lot of players may not make the show but they are playing in decent stadiums for love of the game while getting a useful degree...
