The Mini-Game Drill: This drill is a fun way to practice game-like situations in a controlled environment. Set up a small-sided game (e.g. 3-on-3 or 4-on-4) and play short shifts (1-2 minutes). Emphasize the importance of communication and teamwork, and encourage the kids to try different positions (e.g. defense, forward, center).
