We are just starting basketball this year. Had played 5 games and went to a tournament this weekend and the ref made David take off his pump. He only plays for 3 minute periods so I really didn't want him to take it off. I was ticked because I can't find any kind of rules on Basketball NB's website and it really embarrassed David. One of the other moms gave it to the ref after (I'm too shy to do that). Anyone else had problems or does everyone always take them off?
