What the hell was he doing? Haha. Nice find. I've never really watched a Bucks game. That was hillarious! Did he rather high five some invisible friends of his cos his teammates didn't want to? Or was he practicing his defense? That looked weird. That could unseat Horford for dumbest gesture. LOL!
That is not a gesture. The guy is a poor free throw shooter and he wants to stay in his routine after a flagrant foul and usually there are people giving him high fives. I agree that it looks stupid, though.
