When Thunder point guard Russell Westbrook injured his knee during the first round of the 2013 NBA Playoffs last spring, a lot of people were worried about his future. They thought that the torn meniscus he suffered was going to affect his speed and his explosiveness on the court. They thought that, because of that, Oklahoma City was going to struggle to work him back into their offense. And they thought that they had seen the last of the Russell Westbrook of old.

SO MUCH FOR THAT! Just check out the crazy dunk that Westbrook threw down against the Mavericks last night after driving the length of the court. He has only been back in the Thunder lineup for two games now—two games!—and he's already doing stuff like this. Safe to say, him and his knee are doing just fine and are only going to continue to get better as time goes on.
