Conference Commissioners are too invested in the current model. But that is a reasonable expectation since they live & breath college athletics.
Anti-trust isn't the issue. NIL isn't the issue.
The issue is NBA and NFL owners need to be pushed to fund legitimate minor league system similar to MLB. If Congress wants to do something, they should exert some pressure on NFL & NBA Owners. Maybe threaten a tax on franchise value when it is sold by franchise owners who use public funding sources to build their stadiums.
The other issue that Congress could legislate is the NFL and NBA preventing young men from earning a living by creating arbitrary restrictions when young athletes can be eligible for the NBA & NFL drafts. In MLB the 1st round signing bonus slots in 2021 ranged from $8.4M for the #1 pick to $2.4M for the last pick. In the 2nd round the signing bonuses ranged from $2M to $1.1M.
If the NBA implemented a similar signing bonus structure- I bet most of the top HS hoops players would enter the NBA draft vs. going to college. IMO leveling the talent pool coming into college sports will solve the crazy NIL stuff currently happening.
