I'm optimistic that offering a professional pathway for HS kids who have no interest in college will make the college game better. Scholarship numbers will limit the ability of teams like Arizona, UK, KU, and Duke to turn over entire rosters* every season and we can get back to developing players and winning teams being composed of a rotating cast of juniors and seniors. Sure there won't be as many flashy high end players, they'll be in the NBA, but I think the game will revert to reward fundamentals and development more than "signing" the best pro kids every year.
*I do think a fly in the ointment is an increase in transfer/grad transfer free agency, but maybe that can be overcome with some restrictions.
