Book Review: For better and for worse, the top tier of professional hockey, the NHL, has come to represent the sport. It has, in fact, become the very identity of hockey, writes J. Andrew Ross, a sports and business historian at the University of Guelph. Joining the Clubs is rife with personality, just like the strong-willed, forward thinking individuals who made the NHL possible. Ross’s writing is lively and engaging, and his book is a fascinating look at the NHL in its formative years.
