Jim Montgomery blasts the Bruins for their persistently subpar work, saying, “It’s not acceptable.”

Boston — Not only were the Boston Bruins awful on Saturday. It’s that there may be a pattern emerging.

Their second terrible performance in the previous three games came in a 3-0 loss against the Washington Capitals. They coasted through a 4-1 loss to the Calgary Flames on Tuesday.

It’s unacceptable, according to coach Jim Montgomery. Furthermore, we won’t accept that. We’re going to evolve. perhaps circumstances will shift.

Coaches can put up with subpar performance. Against the Flames and the Capitals, there was a lot of that.

But they can’t put up with shoddy work. Too often, the Bruins demonstrated that they were unable to execute at a professional level, whether it was by losing races, being cautious while approaching hazardous ice, or leaving a battle to avoid being physically penalized.

Montgomery remarked, “I want to break your leg to get the puck if there is one between me and you.” And after the last three games, we don’t currently have that. That’s the crux of the matter. That isn’t appropriate. We simply weren’t good.

During a five-minute power play in the second period, T.J. Oshie put the Capitals a 1-0 lead. There had been a spearing major on Max Pacioretty for Matt Grzelcyk.

Dylan Strome scored during a two-on-one rush in the third. With an empty-net goal, Alex Ovechkin scored his 834th goal of his career.

The Bruins’ power play record was 0 for 4. Three of their four centers, Pavel Zacha, Morgan Geekie, and Jesper Boqvist, combined for zero shots. Compared to his three goals on goal, David Pastrnak deflected six pucks into the goal or wide of the net. The aggressive man-on-man coverage from Washington prevented the Bruins from producing any kind of offensive pressure.

Coyle stated, “Here, we have a standard.” “Tonight, we were not even close to meeting it.”

The home audience at TD Garden voiced their disapproval of what they witnessed to their heroes.

“I cherish our supporters. When asked about his reaction to hearing jeers, Montgomery answered, “That’s what I think.” They are knowledgeable about hockey. They are not incorrect.

Montgomery reached into his coaching toolbox. He reminded his players of their flatline game against the Flames during the first interval. In order to ensure that they didn’t lay another egg, he asked them what steps they planned to take.

After one half, with little to show for it, Montgomery allowed Brad Marchand to speak to his players. That also proved ineffective.

Montgomery moved his teammates about while they were playing. Danton Heinen moved up to the first line alongside Charlie Coyle and Marchand. Pastrnak, Zacha, and Jake DeBrusk skated shifts together.
