My kids all play soccer -the stories ring true to me. I used to coach peewee (preschool) soccer. The crap from the parents and coaches then (kids aged 3-5) was enough to convince me to let someone else take over at kindergarten......
It's funny that there are more parents willing to pitch in at that level than at the absolute beginner level when you need know very little. Of course you do have to be prepared to be on the field, pick the kids up, run, put them down in front of the ball, wipe their noses, tell them to kick, admire the dandelions they've picked while you were wiping their nose ....
