Attackers (A) and defenders (D) each defend a small goal.
A1 plays 1v2 against two defenders. A2 waits next to goal A’s are defending.
A1 can attack defenders or pass back to A2. If A1 passes back, then A2 moves up and plays against D’s while A1 takes spot A2 vacated.
If a defender wins the ball, that D now plays 1v2 against both A’s while the second defender drops back next to goal D’s are defending.
