Kemba Walker isn't known for his defense but after this block on Jose Calderon we might have to change our minds.
I mean, goodness.

That's the kind of chasedown block you don't normally see. Not only is it weird that Walker was able to get back and block a jumper (instead of a layup) he caught Calderon completely unaware.
You would think that a fellow guard might have the sensation of Walker coming back in his periphery but hey, there's a first time for everything.
