2 on 2 close-outs
Coach passes to 1 or 2, defenders X1 and X2 close out into on-ball and help positions.
1 attacks with a limit of two dribbles, X2 can help X1 on penetration. If 1 skip passes to 2, X2 closes out and X1 helps. The attacker without the ball must stay in this area and can only spot up on penetration.
