This is much a sign of the times
In the one and done era of Duke basketball, which has its pluses and minuses, there have been players who had the talent to be one and dones who lacked the skill set to start at the highest level of college basketball. Usually this shortcoming is on the defensive side, although the potential to assess this on the offensive side is limited when there are fewer fixed sets and a more free flowing style is emphasized. When you have a player who is going to be there for four years, if he can't play defense, you coach him up, work with him in practice, and tell him he gets no court time until he can do it. He works his backside off because he wants to play the game. This approach more or less defined at least the first fifteen years of Coach K at Duke .
If he's a potential first round draft pick, you can't do that, or you won't have much luck recruiting the next round of one and dones.
This circumstance, which I am certain has applied to several of our freshmen in the last 6 to 8 years, itself cultivates a lack of accountability. I hate it. I don't enjoy watching it. But these days, it's the price of admission to playing at the level at which we choose to play.
