Another came Nov. 5, 2-1 against the Toronto Maple Leafs, in the sole game between the two best teams in the Atlantic Division.
The Maple Leafs will get another crack at the top team in the Atlantic, and the NHL, at TD Garden on Saturday (7 p.m. ET; NHLN, CBC, SNO, SNW, NESN, SN NOW).
And yet, as Maple Leafs coach Sheldon Keefe said Thursday, "It's not much of a race at this point."
The Bruins (32-5-4) are nine points ahead of the Maple Leafs (26-10-7) in the Atlantic, and as Keefe pointed out, Boston has been on a historic pace.
"They're playing at a pace that's the highest winning percentage in the history of the NHL," Keefe said. "But we would like to make it so that they have to try to maintain that pace or we're going to be right there. So that's really it."
That only means Toronto needs to make the most of its chances.
"They've been the class of the League, for sure," defenseman Mark Giordano said. "We played them early in the year. It was a good game. They're a fast team, back-and-forth sort of game, but [Saturday] it's going to be an exciting game to play in. I think obviously we want to see where they're at and where we're at right now and it'll be a good test.
"If we want to give ourselves a chance of catching them, we've got to chip away, chip away, throughout the next bunch of weeks."
And it's possible the Maple Leafs are catching the Bruins at a good time. There was the hoopla of Boston hosting the 2023 Discover NHL Winter Classic on Jan. 2, a 2-1 win against the Pittsburgh Penguins at Fenway Park, followed by a weeklong trip to the West Coast, where the Bruins defeated the Los Angeles Kings, San Jose Sharks and Anaheim Ducks by a combined 16-5 score.
They'll be two days removed from the 3-0 loss to the Kraken, which led coach Jim Montgomery to mention "mental fatigue" as a culprit.
Then again, the Bruins haven't lost consecutive games all season.
"It's a bigger game than the average regular-season game," Montgomery said. "We need to get our game in order and tomorrow is a good opportunity against one of the teams ... I would say Toronto, Carolina and ourselves have probably been the three teams that have been consistently the best so far this year. So it's a good test for us."
The Maple Leafs will be buoyed by the return of Auston Matthews, who has 47 points (20 goals, 27 assists) in 41 games this season. The forward missed two games because of an undisclosed injury, and then Matthews woke up sick Thursday, Keefe said.
