Each time this is done, it is worth one goal. If the ball goes out of bounds, it belongs to the other team.
Targets can move back and forth along their line.
Have targets look for the player farthest from the ball. Check away from the ball to create space for yourself, check back for the ball at angles. Keep the play in front of you. Never get flat with each other. Take away options for the attackers, make the play predictable, use sideline as extra defenders.
