Duke coach Mike Krzyzewski is known for not using many players in his rotation, especially late in the season, but in 2015-16 this has been taken to the extreme. Injuries and a lack of quality reserves have the Blue Devils effectively using only six players on a regular basis, and each had a major role to play in every game.
However, all six of these rotation players have one focal point that is more important than anything else. It's the area they need to concentrate on the most in order for Duke to be successful, since there's no one else there to do it if they struggle.
