This book did not tell me anything that I didn't already know. When the parents of some of my fencing students saw me with it, they asked me why I was reading it. "I don't think you need to read that; you're pretty good at coaching kids already," was a pretty common statement. I told them that I wanted, more than anything else, to make sure that I wasn't missing anything.
This book would not give the budding youth coach what they really need to get started; that information they'd get from just doing it and talking to their mentor/fellow coaches. In my case, I got a LOT of the stuff the book covers from my three years as a classroom teacher. If you can teach in a classroom, you can handle the non-sport-specific stuff of coaching. This book covers mostly the non-sport-specific stuff of coaching (necessarily).
In the end, reading this book assured me that I'm at least doing the basics correctly and that I'm not missing anything. However, it feels like being praised by an unqualified praiser.
