Centre Sid McNabney is one of just 26 men in history with the distinction of having played in the NHL playoffs, but never the regular season. At no more than 5'7" and 150 pounds, he compensated for his lack of size with strong skating skills and excellent vision and instinct on the ice. The Toronto native first made a name for himself in hockey circles while playing Junior A for the Barrie Flyers in 1948 and 1949. Both years the team advanced to the Memorial Cup tournament, but fell short of the title each time.
Considered too small for the NHL, McNabney was unable to generate direct interest from any of the teams in the league, so he joined the Buffalo Bisons on a minor-league contract, through the Montreal Canadiens. After his second year with the team he had established himself as one of the top playmakers in the AHL, averaging a point per game in the 1950-51 season. The Montreal Canadiens noticed his production and they called upon his services for the 1951 playoffs. McNabney played five games, picking up one assist as the Canadiens advanced to the Stanley Cup finals, losing in five games to the Toronto Maple Leafs.
McNabney was back in Buffalo for the 1951-52 season and also laced up the blades for four games with Edmonton of the PCHL. His last year of competitive hockey was in 1952-53 when he played for the Syracuse Warriors of the AHL.
