I've said this before: I don't like that it's a legit strategy to stick your face in the offensive player's jersey and then get the call when he hits you. I appreciate that the NBA is trying to protect players from head injuries, but at some point players have to take some of that responsibility on themselves. If you don't want to be hit in the face, don't put your face in a place where it's exceedingly likely to be hit.
Rant over.
