Francis Michael "King" Clancy (25 February 1903 – 10 November 1986) was a Canadian professional ice hockey defenceman who played 16 seasons in the National Hockey League for the Ottawa Senators and Toronto Maple Leafs before becoming a coach, referee, and team executive.
Clancy's nickname "King" originates from his father, who was the first 'King Clancy' and played football for Ottawa. At the time the football was not snapped as is done today, but was 'heeled' back from the line. Frank's father was very good at this and was named 'King of the Heelers' or 'King' for short. This nickname was eventually transferred to Frank.
Born in Ottawa, Ontario, Clancy played for junior teams in the Ottawa area and began his NHL career in his hometown playing for the Senators, where he would establish himself as among the league's top players and help the Senators to Stanley Cup wins in 1923 and 1927. Although he was one of the smallest defencemen of his era, he was tough and fast and would not back down. According to Brian McFarlane, it was said that King Clancy started a thousand fights and never won one.
During a 31 March, 1923 Stanley Cup game against the Edmonton Eskimos, Clancy became the first hockey player to play all six positions during one game. In the third period, goaltender Clint Benedict was given a two-minute penalty. At the time, goalies served their own penalties. Not wanting to leave the net open, Clancy played goal for the two minutes Benedict was gone.
On 11 October 1930, coming off what would be the most productive season of his career, with 17 goals and 40 points in 44 games with the Senators, Clancy was traded to the Maple Leafs, with Toronto manager Conn Smythe giving up $35,000 and two players for him. In his second season with the Leafs, Clancy helped his team win the Stanley Cup.
After a sluggish start to the 1936–37 season, Clancy announced his retirement just six games into the season. He retired as the top scoring defenceman in NHL history, with 136 career goals.
