The player driving can scan the field and decide where she will target the drive, and calls out the number of the targeted zone. Her teammates are now informed of the nature of the attack and react accordingly. Positioning again plays a significant role in the outcome of the attack. Sprinting players are establishing position behind the defenders. The goal is being attacked from several angles all at once.
Further pressure is given to the opposing defense just by the rules of the zone system.
They should not cross the center line into their own defensive area. This may create some initial anxiety to a coach at first. But remember, with four or five potential scorers in the offensive zone, the opposing defense must, out of respect, stay in their own end taking some pressure off your own defenders. If a opponent can place nine or ten players in your zone when attacking they will eventually score and you will lose. In the zone, defenders play defense in the defensive zone and forwards play offense and defense in the opponents end of the field.
