Defender x1 starts with the ball and passes to x2. x2 passes to x3, x3 to offensive player 1 as x1 sprints to close out on 1.
 

x2 and x3 close out on 2 and 3, respectively, as the ball is swung around the perimeter. On the first pass, from 1 to 2, x1 jumps to the ball. On the second pass, from 2 to 3, x1 sprints to midline.
 

The offense reverses the ball again, with defenders allowing the passes and working on positioning. x3 jumps to ball then sprints to midline, x2 jumps to ball, x1 closes out.
 

Play live 3-on-3 from here with an emphasis on forcing the dribbler whichever direction your defense dictates. Use this drill to work on the specific footwork and fundamentals taught in your defensive philosophy.
