Query: Great book for my 5-year-old nephew!

My nephew has been obsessed with football from the moment he could grasp a pigskin in his little hands. This book is the perfect combination of picture book and football primer for a 5-year-old. It may also be instructive for people who've always missed several of the more basic aspects of the game. You will know what each player's role is in the game (beyond your basic wide receiver, quarterback, etc), and the key points will be clear. Ahm. Not that you don't already know those things (nudge nudge).
