I'd love to know how many "1-and-dones" over the last 10 years are either starting or getting more than 15/20 minutes a game in the NBA. I'd bet the percentage is surprisingly low. I'm not a fan of t"one-and-done" trend; it makes a mockery of college generally and of college basketball, and it doesn't do a lot for the NBA, either, but I'm not sure what can be done about it. I just saw that there was a commission in 2018 that aimed to make changes to NBA eligibility, but I don't think anything came of it. Look at Keon Johnson and Springer: One year after they were one-and-dones, their NBA teams don't quite seem to know what to do with them. Springer spent most of this past season in the G league--and played fairly well in the G league, from what I read. Keon got some minutes in Portland, but not a lot. They're both quite young and raw, but it will be two more years before either of those guys is ready/good enough to make a significant contribution to an NBA team--and that's typical of most one-and-dones, no? NBA teams draft these guys based on their potential, but first-round picks should be ready to contribute now--not in three years. The 1-and-done doesn't work for the college/college program and it mostly doesn't work for the NBA.
