That was made clear at the 6:12 mark of the second when newcomer Jarred Tinordi confronted Wilson and dropped the gloves in what turned out to be a fairly even heavyweight bout. It was a strong signal that despite having been around for less than a week, the veteran blue liner has come to understand quickly the bond that has existed in the Bruins' dressing room for years.
"What I noticed about this team as soon as I got here is that the boys are playing for each other night in and night out and how close this group is. Not surprised to see the boys respond in a big way after one of our guys goes down like that," said Tinordi.
"You can't have guys taking liberties with our guys out there. That's the way I've always played, that's the way a lot of players on the team play. You've got to recognize that. I thought it was a little bit of a cheap shot. Our guy goes down and we responded in a big way."
The scrap clearly set a fire under the Bruins - Marchand called it the "turning point of the game" - who responded just 31 seconds after the fight when Trent Frederic tapped home his third of the season from the top of the crease to give Boston a 2-0 lead.
From there, the rout was on.
Less than three minutes later, Bergeron ripped one home from the slot after some stellar puck movement off a rush through the neutral zone. After the goal, Bergeron went right to the penalty box to deliver a tap on the glass in appreciation of Tinordi's efforts.
"He's going to be the guy that's gonna lead it," Cassidy said of Bergeron. "He's gonna make sure that he sets the bar, and people will follow Patrice, trust me…he leads by example. He's become more vocal over the years, but it's usually on the ice with his work ethic, says the right things and people fall into place behind him. That's what happened tonight."
Boston added one more with 5:02 left in the second when Marchand notched his second of the game off a pinpoint cross-ice pass from Grzelcyk to put the Bruins up, 4-0. Nick Ritchie then got into the act just 1:05 into the third when he took a filthy backhand saucer feed from Krejci and ripped one by Washington goalie Ilya Samsonov, who took over for starter Vitek Vanecek following the fourth Bruins' goal.
"You hate to see a guy go down," said Marchand, who also picked up an assist. "Brando's a huge part of this team and he's a great player. Most importantly, you're concerned about his health. He was put in a bad spot, but the response was great. Guys went out and did their job.
"It didn't need to be said. They just took control and answered the bell. 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 Brando all game, but we did the job and took care of business on the ice."
