Working on passing is something that should be done on a daily basis, especially with younger players. A team that takes care of the basketball and is constantly moving the ball is very hard to guard. Not only do players need to practice making good passes, they also need to practice catching the ball. This will also help with taking care of the ball during a game.
There a multiple types of drills out there that you can do to work on passing in practice, but this is a great drill for practice because it gets all of the players involved at the same time. Team basketball drills like this allow for a large group of players to all be involved at the same time; which helps to maximize your practice time.
