I know the problem that some parents can cause, but at younger ages it's as much teaching the parents the game as it is kids. The best players tend to be the ones who have parents who work with them on the off days. That doesn't mean you just let them instruct, but if you can get them to shag balls or pitch BP so you can work with a kid that really needs it I think it helps. You might find some good coaches out of the group. TB is much different but still if they can help with field maintenance or shagging,etc I think it helps the team much more than it hurts them.
