You won't know until you give him a try. Monitor his performance if you only get a complaint or two he is probably fine. If a lot of parents are asking for refunds, calm them down, and then give him some help before you show him the gate.

I believe it really relates to the experience that you are trying to give to the players. I have seen it go both ways. On one hand some coaches take too much from the upper levels and try to give the younger players too much information, making the children become overwhelmed. The other side of it was that the coaches had all of the information but could easily tailor it to the level of play. Where the second part came into play and was a real asset was that it could truly be tailored for the level of players. What I mean by that is if young Johnny loves the game of baseball, he has someone that he can go to to learn more about the game and not become bored with the level of his peers.

I know that this was not a real answer to your question, but I think that you have to give it a chance to see if it will work. The big thing that you have to remember is that in any youth organization (actually life in generall) you are never going to please everyone, so do not think that it is a failure because you get a complaint, give it time.

The real thing that you have to ensure is that the coach(es) are onboard with what your organization sets out as their mission. If they arenot on the same page I would not even being down that road.
