The 1921-22 season turned out to be quite eventful. An NHL rule change eliminated the split-season schedule and instituted a playoff between the top two finishing teams. The league also reduced minor penalties from three minutes to two and put a 20-minute limit on over-time. Two youngsters, Frank Clancy and Frank Boucher were added to the Ottawa roster. Clancy scored a goal on his first NHL shot to defeat Hamilton in overtime, even though the puck failed to go in the net.
Ottawa led the league in both goals scored (106) and fewest goals against(84). Although the Senators won the NHL title, the team lost the two-game total-point finals to Toronto. The second game ended up in a 0-0 tie after Toronto won the first match-up 5-4.
Sprague Cleghorn was one of the greatest but roughest defencemen the game of hockey has ever known. After playing the 1909-10 season with the New York Crescents, he went on to play six years with the Montreal Wanderers, a season split between Ottawa and Toronto, two full seasons with Ottawa, four with the Habs and three with Boston. Cleghorn had not been a popular player in Ottawa and, in 1922, when he joined the Canadiens, he appeared to have a vendetta against his former teammates. He died in Montreal on July 11, 1956.
