Maybe not in the NBA, but this happens every now and then in Basketball games... Only puzzies walk off the court after your last foul. You don't leave till youre told.
Just rewatched the Chandler "charging call." I'm not even sure he made contact with another player. It's on calls like this that I'm amazed that at some point a coach just can't take it anymore and pulls his team off the court and takes the forfeit.
