Well, I don’t think the extremes you pointed out are applicable. I think at young age groups, maybe 11 and 12 and under should be developmental based. With rare exception is the best player at age 10 the best player at age 15.
I also think that if your son or daughter is playing at a B team, the coach should focus on nothing but development even at the high school level.
If you can breed development into your club and work on the fundamentals, there isn’t anything bad that could happen. I see so many parents ruin sports for their kids, it’s just insane. Let them have fun and enjoy the game. Once they do, the rest of it takes care of itself. I’m very much along the lines of a Pete Carroll head coach. Work hard and enjoy the game.
I did coach high school football for a couple years. It was one of the worst experiences I’ve ever had. Parents absolutely ruined it. Show me a parent was constantly chirping in their kids ear, and I’ll show you a kid who will be quitting within two years
Show me a coach who makes players run laps, and I’ll show you a coach who is all out of ideas.
I think the first goal in any sport is to make sure the kids have fun. You can still work them hard, you can still criticize, but if they ain’t having fun, they ain’t gonna play. Winning at age 10 is bullshit. Sooner or later, you’re gonna have to win, but it doesn’t need to start at such early ages where parents ruined it for kids. The long, angry car rides home. Yelling at the kid at the dinner table after the game. 100% sport killers.
