Organization - Divide team into groups of three. Each group has one ball. Use a sideline and cones to create a grid 20 yards long. Players lineup on one line. Only ONE player needs a ball in their stick.  Have several groups going at the same time if possible.

Game - On coaches signal, the player with the ball tosses ball about 15 yards into the middle of the grid. As soon as the ball leaves the players stick, the two remaining players battle for the ground ball. The player who gains possession sprints back to the sideline while the other player tries to gain possession. The player who ends up with the ball on the sideline wins a point. He tosses the next ball.
