"It's getting frustrating," Flyers forward Scott Laughton said. "I mean, you lose five in a row, it's tough. [Boston's] a good team over there. … I thought we could have been better, but what are you going to do? You wake up the next morning and practice, and get better."
NOTES: Tortorella coached his 1,400th NHL game. The Boston native became the first U.S.-born head coach in League history to reach the milestone. … The Bruins became the fifth team in NHL history to win their first 10 home games of a season. The others are the 2021-22 Panthers (11 games), the 1963-64 Black Hawks (11 games), the 2016-17 Montreal Canadiens (10 games) and the 1925-26 Ottawa Senators (10 games). … Ullmark became the third Bruins goalie to win at least his first eight home games of a season (Gillies Gilbert, 16 games, 1973-74; Ross Brooks, eight games, 1973-74).
