Create 4 5-10 yard boxes/grids, with 2 lines on opposite sides. There should be a ball on the opposite side, diagonally from one another.  The blue player will run up to the first ball and speed drill to the middle, while at the same time the red player will quickly close down the space, forcing the player one direction. It is important the players get in an athletic stance when breaking down, staying on their toes, side-on, and as they approach the ball, then slightly back off to avoid diving in/getting beat. After the break down, both plays will job back to the line (blue player brings the ball back to line), and red then dribbles the ball in while blue breaks down the play.
