I can make an argument for Kawhi Leonard, who basically ends up guarding the best scorer every night for the Spurs, whether that's LeBron, Carmelo, or whoever. I can also make a case for Hassan Whiteside who is doing man's work down in Miami, grabbing 14.1 boards per game and averaging 2.1 blocks a night for the surging Heat. But we're giving the nod to Draymond Green, despite Leonard's literal grip on the Defensive Player of the Year award the past two seasons. Green just might be the ultimate jack of all trades in the NBA, serving as the anchor to the league's second best defensive squad, according to efficiency rankings. And he's been pretty open about the fact he's low-key gunning to be recognized as the game's best defensive player at the end of the season. Just like Leonard, Draymond usually draws the toughest assignment on a nightly basis. He pulls down more than 8.2 boards a night, averages 1.5 blocks per game, and swipes as many steals a night as Leonard. So the stats are in his favor. His team is obviously the best in the league. And he's a disrupter. That's good enough for me.  —Adam Caparell
