Hi Marc. I'm going to add in a coach, especially of a very young team, needs to know how to bring his/her level of explaining things DOWN to his players level of understanding. He/ She should NOT expect them to bring their level of understanding up to his/her level of explaining.A bad coach....
- Doesn't walk his talk
- Expect things that he doesn't preach (i.e. tells players to eat well and he eats a fries)
- Closed-minded (not open to new ways of doing things)
- Believes he is right and his way is the only way (many hitting techniques works and not every pitching technique works for every body type)
- Believes too much in the "my way or the highway" philosophy
- Lacks interpersonal skills
- Isn't structured - players like structure
- Doesn't have a well-defined coaching philosophy
- Doesn't simplify complex skills when teaching them - too much details and jargon - doesn't keep things simple and progressive
- Runs a practice without prior planning or preparation
- Isn't in it for the kids or love of the game
I could keep going but this is a decent list.
