Duke players who come to the NBA often have a big adjustment to make in terms of defense due to how Mike Krzyzewski teaches that side of the floor.

Jahlil Okafor came to the NBA with questions about his defense and he has predictably struggled.

"I have had several GMs who have drafted young Duke players tell me that the learning curve between the sort of defense Coach K teaches at Duke and what they're required to play at the NBA level is pretty steep," wrote Chad Ford.
