The Boston Bruins continued their historic season with a 3-1 Game 1 victory in the first-round series against the Florida Panthers at TD Garden on Monday.

Boston put together the greatest regular season record in NHL history at 65-12-5, beating the previous record held by the 1995-96 Detroit Red Wings (62-13-7) by three wins.

Kicking off their Eastern Conference playoff campaign, the Bruins jumped ahead in the first period through a David Pastrnak goal, before Brad Marchand and Jake DeBrusk added one each in the second period either side of Matthew Tkachuk's lone Panthers score.

While the Bruins came out with the win, they finished on the wrong end of the total shot count 32-29, also trailing slightly in hits (44-43).

Head coach Jim Montgomery said the score was not indicative of the general play, but at this time of year they will take whatever they can get.

"Results matter more than the process right now," he said. "When we look at our five-on-five game, we were not very happy with our process. 

"So we can get better there, but the result was really good, and I think the result comes from we had some players play really well, especially our goaltender. 

"The intensity of the playoffs, it surprised us a little bit, and I think we had a little bit of nerves."

Marchand is no stranger to playoff hockey, winning the Stanley Cup with the Bruins back in 2011, and he made it clear Boston are not happy with just the regular-season record.

"I don't think we've ever been satisfied with any game we've had this year," he said. "It's always good to start the first game with a win, but we haven't accomplished anything yet."

Tkachuk credited the Bruins with the way they improved the longer the game went on.

"There were parts of our game that were good, and I feel like [the Bruins] got a little bit better as it got on," he said. "Especially when you have a two-goal lead, it's easier to play. 

"You're playing safer, and they packed it in pretty good on us, but I'm confident in our team, in our game, and seeing a lot of things that I think we could hang with these guys."

Game 2 will also take place in Boston on Wednesday before the series heads to Florida.

The Boston Bruins have "much bigger goals" in the Stanley Cup playoffs than a record-breaking NHL regular season.

Boston set a new high for single-season wins with their 63rd against the Philadelphia Flyers over the weekend, and they made yet more history with win 64 on Tuesday.

A 5-2 defeat of the Washington Capitals took the Bruins to 133 points for the season, clear of the Montreal Canadiens' 1976-77 benchmark of 132.

But postseason success is the primary goal for the Bruins. Since winning their sixth Stanley Cup in 2011, this is their third Presidents' Trophy.

That Canadiens team, widely considered the greatest of all time, followed up their regular season by winning the title.

Winger Brad Marchand said: "We have a very special group. It's incredible how we've come together this year.

"We've done a phenomenal job all year of staying in the moment.

"We're proud of the group, but this is a regular-season record. That's not what we're playing for. We have our sights set on much bigger goals.

"I think it [the record] is something we'll look at down the road when we're daydreaming about what we got to do and what we've accomplished."

Boston coach Jim Montgomery was a little more open to discussing the team's latest achievement, recalling the quality of the 1977 Canadiens.

"I think of all the Hall of Famers on those teams and then Scotty Bowman behind the bench and going to the old Montreal Forum," he said.

"Think about how great those teams were and how we've surpassed that total. It's significant because those were dominant, dominant hockey teams."

Boston Bruins winger Brad Marchand says they could not "care less about any regular-season records" as hype swirls about breaking the long-standing NHL points record.

The NHL-leading Bruins possess a 43-8-5 record through 56 games, putting them on track for 133 points which would eclipse the record during an 80-game season of 132 points set by the Montreal Canadiens in 1976-77.

Boston are also on pace for 63 wins which would surpass the single-season record of 62 victories held by both the 1995-96 Detroit Red Wings and the 2018-19 Tampa Bay Lightning.

But Marchand downplayed the significance of those milestones within the playing group who were focused on bigger targets.

"People have talked a lot about some of these records, that we could potentially hit or we have hit," Marchand told ESPN.

"Nobody cares about those in this room. We couldn't care less about any of these regular-season records because they really don't mean anything.

"Before we were going through this season, if you asked any of the guys on this team who owned any of those records, nobody would know, because nobody cares, because it's not about the regular season.

"As soon as somebody brings it up, it's in one ear and out the other."

Marchand added that lifting the Stanley Cup was the goal, rather than records or finishing atop the standings after the regular season.

"If you win the Presidents' Trophy but you don't win the Cup, nobody cares," he said. "That's what we know on this team."
