Query: A must read for anyone who even knows a little about football.

This book starts with Coach Grudens childhood and his involvement with sports. Then takes you through his high school and college years as a player. Then it dives right in with the beginning of his coaching career. As a high school football coach myself, this book has motivated me to be the best coach I can possibly be. By being a constant student of the game. This book is truly a must read for any coach on any level.
