Kawhi Leonard obliterates Damian Lillard with this monster swat

Kawhi Leonard on defense is becoming the equivalent to Stephen Curry on offense -- we're not quite sure if they're human or not, because just when we think we've seen it all, they find a way to impress us yet again.

Leonard isn't the best defender in NBA history, but he's swiftly climbing up the ranks with plays like this. 

When Damian Lillard has a step to the rim, it usually spells trouble for an opposing defense. He's not the fastest or most athletic player, but he's crafty enough to finish with a sliver of space and through traffic.

Leonard doesn't care about Lillard's scoring prowess, though. He sticks with him, stride for stride, and swats his shot into the stands like he's defending a middle-schooler:

It's even worse on Vine:

Lillard is a confident cat, but it's tough to stay cocky after being embarrased like that. Welcome to life when you're trying to score against The Klaw.

Leonard finished with three blocks in the San Antonio Spurs' 118-110 win over the Portland Trail Blazers.
