Pairs of players, each pair with a ball. 2 passes to 1, closes out, and can influence to either side. 1 moves the ball up, down, up, and down. 2 gets one or both arms up when the ball is up, arms down when the ball is down. Then 1 attacks with one or two dribbles, usually at 2's top foot. Next 1 passes to 2 and closes out to continue the drill.
breakthroughbasketball.com - defenders pass from the baseline, attackers are on the foul-line extended or a little further back, then take the balls to the baseline to rotate.
