I think it's more a matter of him feeling right. He's not a good/consistant jump shooter in terms of balancing his body, but today he had it going for some reason. You could see him thinking "I gotta try to remember how I did it" but I doubt we see him shoot this well again this year.
Defensively it was a normal game for him.
