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.

In The Goaltenders' Union, Greg Oliver and Richard Kamchen talk to more than 60 keepers of yesterday and today, finding a common thread in their stories and building a portrait of the goaltender.
