They're running a business, and there is plenty of room. 2-3 more boys will have no effect at all on anyone in any of these age groups. Does it really matter if the kids touch the ball 105 times vs. 110? There's 2-3 coaches on the field at all times, for like 17 kids. Nobody is standing around.

I'd be more concerned if there aren't enough boys to run full field games.

And my son picked up on the Canadian accents right away. He was "thanking the organ-I-zayshun" all the way home (anyone who ever watched an NHL interview will recognize that). These guys are the real deal.
