The Senators, who begin the second round against the New York Rangers with Game 1 at Canadian Tire Centre on Thursday (7 p.m. ET; CNBC, CBC, TVA Sports), had other inspiring sources as well.
Forward Clarke MacArthur, who was told he wouldn't play again this season, returned to score two goals, including the series-clinching goal in overtime in Game 6 on Sunday. That win was witnessed by the wife of Senators goaltender Craig Anderson, Nicholle, who has throat cancer.
Dorion announced Jan. 20 that MacArthur, 32, would not play again this season after he did not get clearance to play following multiple concussions in 18 months, the most recent occurring in training camp in September.
MacArthur continued to work out and returned April 4 to play four regular-season games. He also scored in Game 2, and Dorian said MacArthur personified the Senators' willingness to do the little things to win.
"We were all so proud to be part of the moment where Clarke scored [Sunday], but in the third period he blocked two shots and those could have been goals. I know they scored not long after, but we did the little things."
Dorion said MacArthur repeatedly told him during his recovery, "'I know I can help this team.' Let's not fool ourselves. He helped this team a lot."
Anderson, who took a leave of absence from Dec. 5-Feb. 9 to be with Nicholle while she was receiving treatments for nasopharyngeal cancer, had a 1.96 goals-against average and .924 save percentage in the first round.
