I agree with mawcoach,

Before you switch clubs you I think you should make sure your kid is doing everything at the original club he can to make himself better. I know that most kids at this level do not drill the way they are supposed to. We have some very experienced kids in our club that always want to get better, but they think they are above drilling with the less experienced kids. Not everyone in the wrestling room will have a perfect partner! The experienced kids should drill hard with everyone and help to make the whole team better. It is not a bad idea to find some other work out partners around the area to go live with on occasion, but don't blame other kids for your kid not improving. Unless your kid has more knowledge about wrestling than their coaches I don't think you should switch clubs.
