About Cy Denneny
Lived 1891 – 1970 (aged 78). Cy Denneny was a Canadian ice hockey player and ice hockey coach.
Cyril Joseph Denneny (December 23, 1891 – September 10, 1970) was a Canadian ice hockey forward who played for the Ottawa Senators and Boston Bruins in the National Hockey League from 1917 to 1929 and the Toronto Blueshirts of the National Hockey Association from 1914 to 1917. He won the Stanley Cup five times, four times with Ottawa and once with Boston, and was inducted into the Hockey Hall of Fame in 1959.
His younger brother Corbett Denneny also played in the NHL. Denneny was a member of four Senators Stanley Cup-winning teams; in 1920, 1921, 1923 and 1927. He faced his brother Corbett during the 1923 Stanley Cup playoffs, a series which also featured brothers Frank and Georges Boucher. This marked the first time two different sets of brothers faced each other in an NHL or Big Four championship series.
Denneny was sold to Boston in 1928, where he would be an assistant playing-coach of the Bruins' 1929 Stanley Cup-winner. In 1929, Denneny retired to become an NHL on-ice official. In 1932, he re-joined the Senators as head coach, but the team was in decline due to financial difficulties which forced management to sell top players in order to survive. The team finished last and Denneny was not retained as coach.
Denneny was one of the top scorers in the NHL from 1917 through 1925. While leading the league in scoring during the 1923–24 NHL season, he did so by recording 22 goals and one assist for a total of 23 points, the lowest winning total in NHL history. When he retired, he was the all-time top scorer in NHL history. He was inducted into the Hockey Hall of Fame in 1959. In 1998, he was ranked number 62 on The Hockey News' list of the 100 Greatest Hockey Players. He was the first and fastest player in NHL history to score 200 goals (181 GP). During a six-week span in the 1920–21 NHL season, Cy and his brother Corbett (Toronto St. Patricks), each scored six goals during a game—a feat accomplished by only five other players in the history of the NHL.
Playing style Despite not being a swift skater, Denneny had one of the most deceptive and accurate shots in the league, which enabled him to achieve his scoring feats so rapidly. He was one of the first known players to use opposing defencemen as screens, and would beat goaltenders with head fakes and subsequently with shots that often would not leave the ice. Denneny was also one of the first players to use a curved blade, which he used to take high-rising shots as well as "sinkers" that would fool goaltenders. He was a very physical player who often acted as an enforcer for his linemates, Jack Darragh and Frank Nighbor.
