I disagree - if you have one incredible player at that age, coaches just run up the score at the expense of anyone else on the team getting experience. Experience is incredibly important for developing players. And, at that age level, the disparity between players is due to two factors - skill AND development. The player who is simply bigger for his age doesn't gain skills of teamwork, etc., if you just make him a one man show. When the other kids catch up developmentally, you've already squandered the opportunity for those better kids to actually get much better.
Back when I coached youth soccer, I had a player like that - give him the ball and he could go from one end of the field to the other and score a goal - teammates not needed. He was also bigger than most of the other players, and faster. I limited him to 2 goals per game - any more, and he was benched. BUT, he was encouraged to help the other players score goals. He learned a lot more passing skills, his teammates learned a lot more skills, and we still won. Once that group of kids got to the high school level, they went on to a state championship. That doesn't sound average to me.
