When it comes to defense in the NBA, almost nothing is more important than the interior. Preventing shots in the paint is paramount, as obviously, those type of close-range shots have the highest likelihood of dropping. Because of this, uber-athletic big men who can defend the rim are a valuable commodity in the league, as they can single-handedly turn the tide of a game with their presence in the key -- just ask Hassan Whiteside.
On the other side of the coin, it can be completely demoralizing to have your shot swatted out of the air no matter who you are, especially if you're in a shooting slump. Obviously, the NBA tracks blocked shots as a statistic, but you may be surprised to learn that the league also tracks the number of times a player has been blocked over the course of a season. As you can imagine, there is a host of point guards leading the league in this stat, but you may be surprised with some of the other players who make up this list.
