Like with everything else today, the loudest voices on either side of this debate drown out everyone else. Those who hate it say it's killing college basketball. That isn't true at all. Those who love it act like anyone who ever says anything negative about it is, at best, a selfish fan, and, at worst, a troll and not really a UK fan at all. Again, not true at all.
The reality is it's not the "one and done" that creates the problems. UK has had only a handful of guys leave after one year that shouldn't have. Orton, Teague, Goodwin and Skal come immediately to mind. The problem comes from the culture of wanting to leave as soon as possible, rather than letting the process play itself out. It's like you are a failure if you stay more than two years. And yes, I think that culture is more prevalent at UK than any other program in the country, and yes, I think our coach has created that culture.
The Harrison twins, Dakari, Briscoe, Ullis, Lamb and Liggins are all guys who left early either to go undrafted or in the second round. Maybe I just pay more attention to UK, but I don't see that happening at the other top programs. That UNC team that won the national championship started five burger boys who were upperclassmen. That will NEVER happen at UK while Cal is here. It just won't. We've only had two make it to their junior year here that I can remember (Poythress and Lee), and as I said before, it's not because they've all been huge successes.
That's what causes the frustration, and rightfully so in my opinion. But that's much different than painting with a broad brush that the one-and-done is ruining college basketball.
