Simple answer...YES!
30+ years ago a coach was a drill sergeant and kids responded to that.
Now, a coach has to be a mother, father, big brother, therapist, etc...
They also have to be tactful with their words. Threatening, cussing and berating a player simply doesn't work. The kid will quit or refuse to take part altogether. They have other options.
Also, many years ago a coach was seen as the ultimate authority on their respective sport. Players trusted that they knew what they were doing and had all the right answers.
Now, the world is so connected with information readily available that kids can easily tell if their coach is an idiot or not. Once they lose faith in their coach's ability, it's all down hill from there.
