STEPHEN CURRY, WARRIORS POINT GUARD, +168.17: Golden State head coach Mark Jackson called Curry an “elite defender†earlier this season for the way he has defended shooters over the pick-and-roll and the numbers wholeheartedly agree.
JRUE HOLIDAY, 76ERS POINT GUARD, +150.47: The 6-4, 205-pound Sixer has the body to harass smaller PGs and the 22-year-old energy to do so consistently and continually (+1.1 defensive RAPM, second only to Curry, among the major-minutes players).
JEREMY LIN, ROCKETS POINT GUARD, +137.05: With James Harden taking the bigger offensive load, Lin's D has been key in giving Houston a PG who provides high-pressure defense at all times, ranking second in steals. His court IQ and quickness are some of the most underrated aspects of Lin's overall game.
TONY PARKER, SPURS POINT GUARD, +132.39: Unlike Lin, Parker doesn't gamble, posting a +0.9 defensive RAPM while holding foes to a 13.7 PER. Parker not only provides the offensive blueprint to younger point guards on how to run pick-and-rolls, he also displays the defensive blueprint as well.
