I would not discount a coach for not having played the game, whether they are a Dad or the official coach. Judging by the age group you may be fairly new to the club lacrosse scene. Once upon a time a basketball coach decided to try coaching Lacrosse. He never played lacrosse and somehow was able to start the top ranked club in MD. The coach went undefeated in High School for 7 seasons. He is now in Fla doing the same thing he did in Maryland.
