Let me start by saying there is a lot of information in this book. It is VERY poorly organized. I was expecting this book to be about how Gary Bettman remade the NHL. Instead it seemed like a collection of short stories about things that happened in the league (that mostly had nothing to do with Bettman). Expectedly, most of them are pats on the back. The rest are stories about how he pitted sponsors against each other, handled the lockouts, and pretty much blackmailed cities by moving franchises.
If you are a huge hockey fan and follow the business side of it, it's worth a skim. Otherwise, skip it.
