If he had stayed would he have been picked much higher? Probably not seeing as he was already a top 10 pick. What's to regret? He doesn't have to worry about getting injured, college classes, or if he will ever actually make it to the NBA. If he got injured now he would still have already been paid more than most people out of college, all he has to think about now is getting better at basketball, and he has accomplished something that is simply a dream for most and that is making it to the NBA.
