I don't think either of my sons ever played for coaches that they hated, but both of them seemed to do well with coaches that were a little on the tougher side. Mostly, they wanted to play for coaches who really knew the game and could help them improve and help the team win. I think coaches who personally insult and demean players are wrong, but being tough and holding players responsible teaches them life lessons.
I was very into sports in high school and played for both kinds of coaches. Our girls basketball coach was also the football coach and school "Bouncer" or disciplinarian. When he came to a classroom door to pull a kid out of class for a talk, we all knew we would hear loud noises from the hallway - the kid being slammed against the lockers, etc. Hey, this was the 1970's, and teachers could do things like that. In most cases, if the kid went home and complained, he would not get sympathy from his parents!
This coach looked like a professional wrestler - or a mountain! He scowled a lot and was a scary looking man with huge dark eyebrows and heavy sideburns. He was very tough on our girls basketball team. If we had a bad first half, the locker room would be noisy at halftime ... no girls slammed against the lockers, but those metal locker doors being kicked shut, stuff thrown at the lockers, a lot of yelling and berating for poor performance. I'm not sure it worked well with girls, as most of us found it intimidating. We didn't like the yelling and slamming, but we did want to play for this coach, we wanted to do well individually and as a team, and we wanted to win. He would put us through super grueling practices as punishment for a bad game, with girls getting sick etc., but we would keep pushing ourselves to do what he demanded. I can't remember any girls ever complaining to their parents, and I can't remember anyone hating him. Fearing him a little yes, but not hating.
A few years ago I went to a girls' basketball game at our old HS, and was surprised to see him still coaching (it was about 25 years after I graduated!). I didn't see him yell at all during the game - maybe yelling at girls is not accepted as much these days, or maybe he mellowed from his late 20s to his early 50s. I got a chance to visit with him for a few minutes after the game, and did feel happy to see him and talk to him. Thinking back now, I believe playing for that man for 3 years was one of several influences in my life that made me tougher and taught me how to keep giving everything you've got even when you are just about to puke. That is sometimes useful in the working world, too, LOL.
