No coach would attempt to play an entire game with only one group of players, leaving most of the players on the sidelines. Player fatigue would quickly become a problem. Yet, many youth coaches fail to take advantage of their "extended team" (the parents) and feel fatigued themselves by the end of their season.
Successful youth coaches look at their team not just as a group of players, but as a group of players and their parents. Just as coaches don't hesitate to ask for participation from players at practice, coaches shouldn't hesitate asking for participation from parents.
Coaches have a large burden preparing for practices and leading a team during a game. They only make it harder on themselves when they try to do everything. Asking parents to help with items such as snacks, water bottles, and parties is the best way for coaches to fully use their extended bench.
