Query: A must-have for all coaches

A friend of mine had this book; and I thought my husband, a high school wrestling coach, would really like it. It ended up being one of his favorite gifts from me. He had it for several years when he loaned it to one of his wrestlers who was designing a team shirt. We never did get the book back, so ended up buying another copy. This year, my husband had a senior wrestler graduating whom he had gotten very close to. He decided that this book would be a wonderful graduation gift - which it proved to be. After purchasing 3 copies of this book, I anticipate having to buy more in the future, and each will be well worth the money. :)
