Jeff Marcus goes all the way back to 1904, the date of the first openly professional hockey league, the International Hockey League.
He goes on to cover all the coaches in all of those early leagues including the Ontario Professional Hockey League, The Eastern Canada Hockey Association, the Pacific Coast Hockey Association, the Western Canada Hockey League and the National Hockey Association. Of course, that NHA would later be reformed into the National Hockey League.
Marcus moves away from all the obscure pro leagues that littered the 20th century but does focus on all WHA and NHL coaches, right up until the current day.
We speak with Jeff Marcus about some of the best known coaches, some of the longest standing coaches and some of the most obscure coaches.
