The only connection would be if the coach knew a young man was in a 'worked up' state and left him in to play. I'm not saying this is what happened in this instance. Otherwise I am in agreement with you that a ref, coach, or parent is not responsible for throwing the punch here. But, if they fueled the fire that led to it are they an accessory? I was being more general because I feel this won't be the last fight that breaks out in a soccer game. Authority for control on the field and consequences should be clearly outlined now that there have been at least two events.
