Coach Ray Tomberlin, Coach Tomberlin, I am not sure if it is the same one I am going to describe but this is the one I was taught at a early age and have continued to use through the years. Put 3-4 players in a line in each corner of the half court area. Start simple with just two balls, opposite corners from each other. You basically have two options, either an outside cut, pass and fill, or an inside dribble, pivot, pass and fill. Start your drill by just allowing the outside cut.
Coach calls the direction, right or left.
Be sure to allow enough time to let your players process your call and physically change directions. The more skilled they become the faster you can call changes. Start early in your drills to test their concentration by having the receiving player call the name of the passer. This teaches unfamiliar players to learn teammates names but more importantly teaches on court verbal communication a much more important skills that most coaches realize and emphasize in practice. Once the team can move at a reasonable speed, execute the fundamentals without error, and reverse from right to left on calls, speed up the drill, and even change the pivots.
