Backcourt violation could possibly be on this list, especially when the entire gym sees little Johnny or Sally bringing the ball up the court and never completely comes into the frontcourt (1 foot and ball in frontcourt, other foot on the division line) and returns completely into the backcourt. THAT'S A BACKCOURT.. I KNOW YOU SAW THAT MR. REF!! My response is usually I saw what you saw, but one of us knows the rules and the other doesn't.
