I think “one and done” has done a lot to damage college basketball.
Most who jump to the pros are immature, and don’t know how to handle the situation. And most of those who jump also end up leaving the NBA after a short stint. With no college education, most end ul flipping burgers. The lucky ones can at least play pro ball in Europe.
But even if they manage to complete their four years of eligibility, most are still quite uneducated and unprepared for the real world. So if they don't make it as a pro, they're screwed. Bankrupt, uneducated, and just another person on gov. system and/or into crime.
Some coaches are running basketball camps and basketball entertainment enterprises under the umbrella of a university. It is interesting how you can find every minute detail about their basketball performance and nothing about their academic performance. Maybe all basketball scholarships should be for a minimum of 2 years. If you leave after the first year the school is still charged with a scholarship for the second year.
