And now I'm chiming in - different YJ Parent than above - My daughter has had all adult coaches throughout YJ career. Love them or not (which we pretty much liked them all), every one of them were committed adult coaches with varied experiences and years of coaching on their resume. YJ draws mostly good coaching resumes, CR can and is focused on a winning program, so Winning Coaches come forth and it's a good fit. Sometimes a coach hasn't met expectations, we can see that. But our experience is precisely this :
Credentials - It's a good mix really - many High School long time career coaches, college coaching experience, youth/club/ms/hs/ college/professional playing experience, many Championship teams on all levels, Trained and certified Coaches, Coaches of multiple sports. All were Adults, with careers - they can manage adult roles running teams, managing people ie Educators, Professors, cops, fire fighters, business careers. In the end, their credentials also include the organized practices - set schedules, seasonal/year round marathon sessions of training on field - hours of intensive, organized work as a Team practicing. This produces skills, team play, IQ, desire to win. We have had some college aged assistant coaches/helpers to our teams, who while they may wear flip flops, they served a key role on our teams as an assistant (one of two assistants to the head coach ) - the girls relate, they have strong vision of the field of play, teach skills, they are committed to the role they took on. We have experienced one consistent thing - our coaches used their experience, took on the role with YJ, and they meet their commitment of time and teaching lax to kids using their extensive Credentials. Just like any good program.
