We have all of the athletes make two lines about 100 feet apart. We then throw a ball in the air. We make the players call ball by yelling ball, ball, ball, and then we have the other playe acknowledge by saying you, you, you. This does two things. First, it reduces injury and makes sure the ball is going to be caught. Secondly, it gives the athlete confidence to catch the ball with the acknolwedgement of the other player.
Both of the players go hard to the ball at all times until one finally calls for it and the other acknowledges. This communications is essential for confidence and reduction of injury. We also tell the athletes to never acknowledge until the ball is called. In other words, do not say you, you, you until someone calls for the ball. We don't want a player making a decision for another.
