Boston Bruins coach Jim Montgomery has learned to normalise the success of his team this season, even as they made NHL history on Thursday.

In beating the Buffalo Sabres 7-1, the Bruins improved to 48-8-5 and 101 points for the year.

The Bruins passed 100 points in their 61st game, beating the previous record set by the 1976-77 Montreal Canadiens, who reached that mark in 62 games.

But Montgomery was relatively unmoved by the achievement, having grown used to his brilliant team setting the benchmark over the course of the campaign.

"For me personally, it doesn't mean that much," the Boston coach said. "We try to stay in the moment, and we've been doing that.

"We started off 11-1, and I was like, 'man, that's unreal,' and then you catch yourself and you go back into the moment, and we've probably gone 11-1 every 12 games to have the record we have.

"It's been really amazing to watch them want to be great, because with the schedule and everything, it's really impressive."

The latest win came on an eventful day for the Bruins, who tied David Pastrnak to an eight-year, $90million extension earlier on Thursday.

Pastrnak then had a goal and two assists against the Sabres just hours later.

The Bruins also traded for forward Tyler Bertuzzi from the Detroit Red Wings ahead of Friday's deadline.
