The streak is the longest to begin a season in Bruins history.
"It says we can win games in a lot of different fashions," Bruins coach Jim Montgomery said. "It says we're deep, and it says we have great leadership. I can't compliment our players and the commitment to the team by their attitudes enough."
Connor Clifton had a goal and an assist, and Hampus Lindholm had three assists for Boston (14-2-0), which has won four straight, including 3-1 against the Buffalo Sabres on Saturday. Linus Ullmark made 29 saves.
"We're a really good hockey club," Lindholm said. "[We've] got good pieces here, but it's going to be a long year. Like I said, I'm [prouder] of the group for that process there from Buffalo. Like this learning, adapting, that's how this season's going to be. It's going to be a lot of hurdles, and we just have to keep going [in] that direction."
