The Stanley Cup champion Ottawa Senators were on the verge of staking their claim as the NHL's first dynasty. During the 1920-21 season, Ottawa featured Clint Benedict as the league's finest goaltender, while forwards such as Cy Denneny, Jack Darragh and Frank Nighbor ranked among the world's best. Not to be outdone by his brother Corbett who had six goals earlier in the year, Cy Denneny scored six times against Hamilton on March 7. He finished second in the NHL in goals, with 34.
In the Eastern playoffs, Ottawa shutout Toronto 5-0 and 2-0 before going west to meet the Vancouver Millionaires for the Stanley Cup. In front of 11,000 spectators, the largest crowd ever to see a hockey game in Canada, Vancouver won the opener 2-1. Ottawa took the next two games before Vancouver tied the series at two games apiece. In the deciding game, 2,000 fans were turned away for the game won 2-1 by Ottawa on two goals by Jack Darragh. The Cup remained in Ottawa.
