Here are a couple of great drills designed to maximize your player's development with passing the ball.
Monsters On the Loose
Set up a 15 x 15 playing grid. Two players jog around the outside of the grid and act as the monsters. The remaining players should be broken up into groups of two. They move the ball around the inside of the grid by dribbling and passing. When you call "Monsters on the Loose", the outside players rush in and try to kick the balls away from the pairs. The monsters may not double team any pair of players. They must act independently. The pairs should try to move and pass to keep the monster from getting the ball. Play for a minute, then change out the monsters and do it again.
Number of Players: 2 Monsters, plus pairs of two
Equipment: A ball for each pair. Cones to mark a grid.
Air Ball - Passing & Receiving
Split the players up into groups of three. One player will hand pass the ball in the air to a second player. The second player must receive the ball in the air and touch it to a third player. Keep the players rotating after a few successful combinations.
Number of Players: Groups of 3
Equipment: Each groups needs a ball
