Clarify "no coaches coaching teams playing"
There were a few teams that had no coach coaching them.
If there was coaches coaching them then you would have the people saying the coach was bias and set things up for the kids he wanted to, or gave some kids more playing time. I thought the kids did a decent job being fair. The biggest issue I saw is that they need to rotate the face off middies. My son (an attacker) was on a team with a kid who won 1 faceoff in 2 games. Needless to say the other teams had the ball 75% of the time. there probably should be some 1 v 1 - 4 v 4 drills so that you can see what kids can do. Then scrimmage for half.
