I think if he was making like a million a year and was around 20-30 in the draft projections that he could go back.
It's tough because even as a late first round pick he'd be making double that on his rookie scale and also have the second year guaranteed. I think NIL can serve as some security for first round guys if they want to try risk it and improve their draft stock, but I probably would probably still advise against any player skipping the draft if they are a first rounder.
