Note on Basketball Referees 

Keep in mind that the referees are there to make the game better. Without officials the game would be no fun at all and they are doing the best they can. They WILL make mistakes. Basketball is a difficult game to referee. That's just how it is. Getting angry, yelling at the ref, and throwing a fit does no good and will not help you or your team. Just keep playing and listen to the refs regardless of whether you agree with the call or not. Move on to the next play. They are doing the best they can and are trying to make the game enjoyable for all.
