I thought this was a decent book for a couple reasons. I think that the information presented in this book is unique to the sports genre. The book is interesting and full of images, facts, and labels that immediately draw the reader in, but may be slightly overwhelming at points. The writing is clear and simple while still being thorough. The book is organized into different "levels" or chapters to help the reader find the type of sports knowledge they are searching for. The big idea behind this book is to provide explanations for specific sports questions such as, "Why is there a shot clock in basketball?" or "Why are there nine innings in baseball?"
