Late in the ECAHA season, the Cup trustees decided that Ottawa should defend the Cup against Smiths Falls, champions of the reconstituted FAHL. Frank McGee notched nine goals in the two games, which would be the last of Ottawa's nine straight successful Cup defenses.
It is interesting to note that the title "Silver Seven" was given only to the team and not to any particular seven players. Ottawa's line-up included a total of 16 players during its Stanley Cup reign that spanned from 1903 to 1906.
Ottawa and Montreal each concluded the regular-season at 9-1-0, leading to a two-game, total-goals series for the ECAHA championship and possession of the Stanley Cup.
In his Stanley Cup debut, Ernie Russell scored four goals to lift Montreal over Ottawa 9-1 in the first game, which left the defending champs with the task of outscoring the Wanderers by a minimum of nine goals in the second in order to retain the trophy.
Ottawa unveiled Smiths Falls goalie Percy Lesueur in goal for the second game, and after he gave up an early goal, Ottawa stormed to a 9-1 lead on the strength of Harry Smith's five-goal effort to tie the series. However, Montreal rover Lester Patrick scored two late goals for the Wanderers to lock up the club's first Stanley Cup title.
1905-06 - (Mar.) - Montreal Wanderers - Henri Menard, Billy Strachan, Rod Kennedy, Lester Patrick, Pud Glass, Ernie Russell, Moose Johnson, Cecil Blachford (Captain), Josh Arnold, Dickie Boon (Manager).
