Has Duke become a shameless basketball factory?

Note two very interesting occurrences at Duke within the last week or so. Both of them do not reflect well on the college juggernaut Mike Krzyzewski has built at Duke, the same juggernaut that now feels like a revolving door turning for his own benefit.

That revolving door serves to usher one-year players like Trevon Duval and Gary Trent Jr. out of town, hopefully not hitting them in the backside as they leave. Duval was always going pro after one year for several reasons that reportedly range from academics to a purer point guard named Tré Jones coming in to take his place.

The media has said that Duval and Trent became bad fits for the Blue Devils, who played two big men and a zone that cut down on their transition game, which would have better showcased Duval and Trent. Now they’re being treated like there is no room for them with another top-rated recruiting class coming in.

Problem is that over the course of the season, it developed that Duval and Trent are no longer projected as first-round NBA draft picks.

The other news is that Wendell Carter Jr., who manned the double post with one-and-done Marvin Bagley III, is now reconsidering turning pro when his mother said right after Duke’s season ended that her son was gone. This smells a lot like Coach K trying to get him to stay so he’ll have an experienced big man.

Krzyzewski has done this before when he wanted five-star recruit Marquise Bolden to return this past season so he could play more than he did as a freshman. That was before Bagley jumped right from his junior year in high school to Duke. Is Bolden now being bypassed again in favor of Carter? Frankly, this is all very un-Duke-like.

After once having a model program that balanced great academics and great basketball, Duke now has had 14 or 15 one-and-dones since 2011, depending on whether Carter goes. This has rankled faculty members and Duke fans alike.

Krzyzewski might have his reasons, but he has had one Final Four team since 2010, while Carolina has had two and won more NCAA games by developing players. Now another 5-star class is coming in and all of them think it was in their best interest to pick Duke. For some, that’s true. For others, lately that choice has hurt their NBA chances more than it has helped them.
