Hi Coach, I think the key is to first understand the situation more, if you can without overly intruding. Is the player giving any reasons or signals as to why? There’s a chance there’s something going on in his life (family, friends, etc.) that is affecting his behavior. It might not be a good idea to push him too much until you really know what’s going on. If you can understand what’s in his mind it should be easier to figure out an approach. Once you do that, going to a college or NBA game might help. Is there a very skilled player several years older that you can find that might be willing to be a mentor?
