Gerald Green's missing digit

Hey guys, did you know that Gerald Green has a short ring finger on his shooting hand? I know he can dunk and shoot the 3 well, so it suprised me to see that he was missing part of a finger.

It obviously doesn't affect his shot much if at all. Although it is quite suprising to see his hand when he dribbles and shoots which made me wonder, does his missing finger help or hinder him?
