Seems like the simple solution would be to continue to bar boosters from being involved with players and recruits, including businesses that said boosters are involved in.The schools would be the biggest losers. Instead of the funneling money into the AD through charitable donations, boosters would pay players directly for marketing services and write it off as an operating expense in their business. The student athlete would no longer care that much about the fancy facilities since they can just rent a sweet pad with their own cash.
If I’m Phil Knight why can’t I pay every single player $100,000 per year for marketing? Why even have scholarship limits anymore? Phil Knight will pay your full cost of attendance and more for marketing services rendered. Doubt it goes that way, but interesting to speculate how a billionaire could basically just buy the best team, assuming money would be a players primary concern.
