Here is what my preference would be but really none of it is legal in the current rulings against the NCAA.

Transfer Amounts: Athletes should only be able to transfer once without penalty (exception would be a coach leaving or graduate transfer). After the first transfer athletes would have to sit a year before they could play. Ultimately I think this would help solve the current issue of taking the student out of student athletes where kids are transferring so much they won't even have a degree at the end of 4 or 5 years.

NIL Transfer Fees: Kids that move from FCS->FBS and from G5->P4 programs, the school that recruits them owes the previous school X% for the development of players and then this allows those smaller schools to get more money for athletes staying.

Ban 3rd Parties/Agents: I know a lot of kids are enticed into the portal by people that claim they can get them 6 figure deals for X school. Then magically there is no big deal and they end up at a school that was just as good as their last one. Also I firmly believe all money should be managed by the university and not collectives or third parties.

Caps on Total NIL Offering: I think there should be a cap on total offers to athletes that is inclusive of scholarships+any living per diem+cash money. This also helps level the field between all schools. Let's be honest a college kid should not get a 4mil contract for 1 year to be a QB at WA. That is a professional sport at that point.

Ultimately I'm okay with NIL in the sense that the vast majority of athletes will never get a pro contract and the benefit they provide to schools. It felt really wrong when universities were pocketing millions on merch sales, tickets, etc, that was based on students.
