The victory propelled the Bruins to their fourth victory in five games to start the 2019-20 campaign, a quick start - both for the year and the game - that they credit to the team's cohesiveness and familiarity.
"It helps having pretty much the entire group from last year - a couple new guys - but for the most part we're the same and it makes it very easy to find chemistry and to just roll back into the season and keep going," said Marchand, who notched his 300th career assist on Patrice Bergeron's second-period power-play marker.
"That's kind of been our mentality, let's just keep the ball rolling. We know we compete hard, we know we have a good group and we're well conditioned...it's been very easy, again, because we have pretty much our whole group together."
Boston outshot the Devils, 15-10, in the opening 20 minutes, converting for two even-strength tallies in the first 11-plus minutes of the game to open up a 2-0 advantage. Marchand got things going, continuing a torrid stretch with his fourth goal of the season just 3:33 into the contest, a long-distance wrister from the top of the slot that deflected by Cory Schneider to put the Bruins on top early.
"He's on right now," Cassidy said of Marchand, who extended his points streak to four games. "That line seems to be clicking like we've seen them typically…our offense is coming to form now, I'd say, probably since Vegas. Colorado was good, and tonight we certainly had good opportunities as well."
The Bruins doubled their lead at 11:22 of the first when Joakim Nordstrom picked up his first goal of the season, connecting with fellow fourth liners Sean Kuraly and Chris Wagner off a faceoff win to whack one by Schneider for a 2-0 advantage.
"They did what they typically do, which is play against good players, manage the puck, check well to get it back, long shots, killed penalties," said Cassidy. "They were able to chip in offensively - I think it picks everybody up on the team when they get rewarded because they do a lot of the grunt work, rarely see the power play. When they get opportunities to finish, I think it picks up our team."
