I wouldn't be surprised if he returned either. I do remember he wanted to go pro after his freshman season, but came back after the scouts told him he wasn't a lottery pick. Guess his draft stock has never really improved and as you pointed out, NIL makes a huge difference these days.
I don't see Davis being UNC's coach for longer than two more years. He might not last that long. Seems things never last long for guys that follow a legend, especially if the team/school has better options available.
