Over the years I've seen many types of coaches. Some are good with youngers, some are good with olders, some are excellent trainers but can't game coach, some are excellent game coaches but can't run training, some are very good recruiters and don't need to coach, some have to coach their ass off because they can't recruit. They come in all shapes and sizes (and accents). Former professionals and people who never kicked soccer ball in their life. Many former pro's think they can coach because they played - not necessarily true. Coaching is an Art - you either can do it or you can't. Many tried and more will.
For me personally, if I remember the coach - he/she did something right.
Agreed, this guy never screams and I've seen plenty games he coached.
