Three attackers pass and dribble through two zones, each with one defender, to score.
Possible rule
Attackers must play 2 touch in zones 1 and 3. This forces passing in zone 1 and quick finishing in zone 3.
Rotate
Rotate defenders after 2 to 3 minutes, or have them rotate naturally if they steal the ball.
When to pass versus dribble. Balance and support in attack: a triangle shape, with depth and width.
