No reason to criticize anyone being paid for a service if they are legitimately providing assistance . One of the coaches at our HS runs camps all summer long, on the Island and upstate, and VERY profitable it is. Not lacrosse but another sport, however, he NEVER goes to bat for any of the kids he wines and dines in HS promises them the moon and stars. He is too concerned with building his empire within school, to even think about what these kids are sacrificing. Meanwhile they are thinking (as are the parents) they might have a snowballs chance in h e l l of getting recruited with his help. Doesn't happen never has never will.
Showcases and tournaments on your own at club level is the how it happens.
