There's nothing wrong with this book, but there's nothing especially excellent about it, either. As another reviewer or two have noted, the main points in this book have been covered extensively by many other media outlets for many years. I'm not sure why a publisher would want to pay Mark Hyman to duplicate excellent magazine and newspaper work by him and many others, except that it's a hot topic.
Hyman visits interesting places and does some first-hand reporting on some of the egregious businesses that have arisen in the sports-industrial complex, such as the communities that host youth sports tournaments or the hucksters who claim that their videos will get kids college athletic scholarships. Reading about that stuff just makes me glad that my teenage son is content to play community-level sports once a week, and that I can be an occasional substitute coach.
The book suffers from a few things that probably reflect a rush job. First, the preface states (I'm paraphrasing) that the book will follow the travails of three disparate families who have kids in competitive sports. But the author references them only in one chapter, and the three families are hardly representative of anything, given that almost all of the parents are journalists and artists. Second, there's a chapter about corruption in urban sports leagues that are trying to groom the next NBA star, but I'm not sure what that has to do with sports in upper-middle-class suburbia, which is the focus of the rest of the book. And third, a few folks in the book are criticized for their actions in 2009-2010, and the author makes a point of saying they haven't cleaned up their act. But he wrote the book in 2011, so it's not like they had a lot of time to adjust.
In short, if you're new to the topic, this book is a good introduction. If you're already entangled in youth sports, this book is a reminder to keep your perspective and to watch your wallet.
