We are all role models for children - parents, coaches, referees, administrators etc.
Perhaps we can't be all of the time, but we can for most of it.
Parents should not abdicate the role to coaches, but coaches need to accept that they are a role model too.
Over 20 of coaching has had some wonderful rewards in watching children develop into young adults. Few have gone off the rails.
Sport can teach kids a bunch about life, and coaches can assist that. We do win, and we do lose, teach them how to deal with that. Philisophical, i know, but it's a real outcome for kids in sport.
