Agreed. I don't see a whole lot of incentive for a 5 star high school player to join a union. It's why I don't think the landscape is going to change much, going forward. They can't force a union on the players. And without one there's no CBA. And without a CBA, the restrictions that the schools would like to enforce are illegal.
At the same time, for all of the chicken little-ism going on, bemoaning the death of college athletics, we're still seeing high consumption of the product. The games this weekend had the highest ratings since 2017. A credible argument can be made that there really isn't a problem.
