@Linkat,
Yeah, that stuff sucks. I haven't run into a lot of it but the one soccer coach that I keep complaining about is like that. During the regular season with him and another coach (who was much, much better) the girls were undefeated. Now in this other league (many of the same girls, a few others), he's the only coach and they're not doing well and he keeps going on about how they need role models and they need to work harder on this and harder on that and ya know what, HE needs to lighten up! It was nice when they were winning but it's really not the end of the world if they're losing (and good for them to have some real competition instead of just smushing everyone they played against).
Edit: plus he wants them to keep going (in yet another indoor league, this one was brief), many of them have basketball starting, and I do worry about overuse injuries. I mostly want my kid to be fit, strong, and have fun, and if some sports skills emerge from that, coolness. I DON'T want to do that specialization thing (pick a sport at an early age, practice it incessantly) which I think is dangerous.
