Below is a drill designed to help your defense and passing, but also increase the intensity and energy level in the gym. Anytime you can run a drill that teaches a skill and increases your intensity and energy level, you should consider adding it to your practice. These type of drills not only teach a skill, but effectively increase the effectiveness of subsequent drills in practice.
