[Ref in PA]

Also, the angle of the "pull away" will help the ref see what is going on. If the ref is on the base line and B1 is behind A1, holding A1, if A1 moves toward the center of the court, the base line ref is less likely to see the hold. If A1 moves toward a sideline, the jersey grab will be more obvious. Have your players manuver to give the ref the best possible angle.

Know also we expect the players to play through minor inconveniences. Have them do their best to play their game and this should illuminate to us if they are really being impeded or not.
