In hockey, goalies have always been a contradiction -- solitary men in a team game, the last line of defence and the stalwarts expected to save the day after any and every miscue and collapse from his teammates. It's no wonder that anyone who played the position has had his sanity questioned; yet some of the biggest innovations in the game have come from its puckstoppers. In The Goaltenders' Union, Greg Oliver and Richard Kamchen talk to more than 60 keepers of yesterday and today, finding common threads to their stories, and in dozens of interviews about them with other coaches and players. From Gilles Gratoony the Loony Gratton, who refused to play because the moon was out of alignment with Jupiter, to Jonathan Quick, the athletically gifted master keeper of today's game, the book is an entertaining and enlightening peek behind the mask.
