Marchand gave the Bruins a 1-0 lead with a backhand from the slot at 14:21 of the first period. Trent Frederic made it 2-0 on a redirection of a McAvoy pass at 6:43 of the second period.
"I thought the response was great," Marchand said. "The guys went out and did the job, it didn't need to be said. They just took control and answered the bell [physically]. And as a team we played the right way after that. We didn't let it distract us or get us down. Obviously we were thinking about [Carlo] the whole game, but we did the job, took care of business on the ice."
Bergeron extended the lead to 3-0 on a one-timer from the slot at 9:01. Marchand scored his second goal of the game at the side of the net to make it 4-0 at 14:58. Nick Ritchie made it 5-0 at 1:05 of the third period with a one-timer off a cross-ice pass by David Krejci.
Jakub Vrana ended the shutout at 13:36 with a shot from the right face-off circle to the far side that made it 5-1.
"There was a time of the [second] period where we did some mistakes, and a team like that's going to take advantage of it," Vrana said. "They score a couple goals there, and since that we kind of struggle to find our game back. It is what it is, and now the only thing we can do is to learn from the mistakes we did and then already put this game behind us and focus on the next game we have in front of us now."
