The tittle of "shutdown defender" is elusive because it is not easy to measure how great a player has been defensively.
Today we have such advanced stats such as plus/minus which tells you how a player affects the score while he is on the court. But that cannot be properly assessed to all players at Duke over the years without the proper resources.
Nevertheless I have compiled a list of players who deserved some credit for their defense. Some paid more attention to the defensive end of the basketball court than their own offense and took pride in being able to give opposing players a bad night.
This is a tribute to those guys. Most may not be great scorers but they stole the ball at a high rate, blocked shots, or when they were in the game the opposing team's offense stagnated.
