They held court on home ice in dominant fashion, but as the series resumes in Toronto, there's still much work to be done.
"You want to keep your foot on the gas because this team has had success against us in the past and they've done a good job playing us, especially in their building," Backes said, according to NHL.com's Amalie Benjamin. "Complacency is probably the enemy at the moment, but we need to go start from the puck drop. It's a 0-0 game, and establish ourselves again."
Key to Boston's success has been the play of the top line, as David Pastrnak, Patrice Bergeron, and Brad Marchand have already combined for 20 points (five goals, 15 assists). For his part, Backes is wary of relying on that formidable trio to keep getting the job done.
"The rest of us, we need to make sure that we're not just saying, 'Well they're going to have another awesome night tonight,'" Backes added. "If we're going to just sit back and wait for them to do it, if there's a night where they just don't have it, or they don't get a bounce or two, we need secondary scoring to step up and make sure we have that."
Backes, who's been to the conference finals only once in his career, has recorded one goal in the playoffs so far.
