The Most Efficient NBA Players At Each Position 

Center - Hassan Whiteside, Miami Heat

Defensive Player of the year?

Agent Block, as he likes to call himself, is currently the best Defensive Player in the NBA.

Young Whiteside is famously known for blocking and catching the ball mid-air from players instead of just blocking it away.

Unfortunately, Whiteside is injured and is unable to play for the Miami Heat. But when he's healthy, He is a Defensive beast on the floor. He made a whopping 161 blocks last season.

With the Heat hoping for another playoff appearance, they will be relying on the 7-ft Shot Blocker. Whiteside is expected to return by the end of the year.
