Boston Bruins coach Bruce Cassidy has one season remaining on his current contract, but discussions are expected to begin this summer on an extension.

Cassidy, 54, guided the Bruins to Game 7 of the Stanley Cup final before losing to the St. Louis Blues. Overall, he has a 117-52-22 record in 191 regular-season games behind Boston’s bench, and the Bruins have earned a postseason berth in each of his three seasons as their coach. His current contract expires after the 2019-20 season.

“He’s under contract, so we have decisions that we’re going to progress with, and he’ll be part of that,” general manager Don Sweeney said. “He’s under contract, so it’s not a concern right now, but we will address it.”

En route to the Stanley Cup final, Cassidy outcoached Toronto’s Mike Babcock, Columbus’ John Tortorella and Carolina’s Rod Brind’Amour. The Blues’ Craig Berube proved to be the Cup-winning coach.

Babcock, who won a Stanley Cup with the Detroit Red Wings, earns $6.25 million per season with the Maple Leafs. Former three-time Cup-winning coach Joel Quenneville with the Chicago Blackhawks was recently given a five-year deal worth $5.25 million per season. New York Islanders coach Barry Trotz, who won a Cup with the Capitals in 2018, earns $4 million per season.

The Philadelphia Flyers recently named Alain Vigneault coach and gave him a five-year deal worth $5 million per season. New York Rangers coach David Quinn just completed his first year as an NHL coach, and he earns $2.4 million per season. Even recently named Buffalo Sabres coach Ralph Krueger, who hasn’t coached in the NHL since 2012-13, is making $3.9 million per season.

Safe to say Cassidy deserves a pay raise and job security.

“It’s something that obviously Don’s got to deal with this offseason, and then he’ll talk to me about where he thinks it’s going to land,” team president Cam Neely explained. “Yeah, the landscape has changed a little bit, so Don will certainly start those conversations with Butch and his representative.”

While the Bruins begin their offseason preparations, Cassidy will undergo a knee replacement next week, and his rehab is expected to take the rest of the summer. He’s expected to be ready for training camp.

Meanwhile, discussions will begin on a possible extension for the coach. The process likely will begin after Sweeney handles the upcoming draft, development camp and free agency.

“For me, it’s about going to Charlie and Mr. Jacobs with what I think we need to do and what I would recommend,” Neely said of Bruins CEO Charlie Jacobs. “Generally speaking, if it gets to that point and they ask me, ‘Is this what you think we need to do?’ They want to know what’s going on, but they also want us to do our jobs, so the success that Butch has had everyone recognizes the job he’s done and how successful the team has been, so we’ll see where it ends up.”

Neely said he would recommend an extension for the coach.

“Depending on the price,” Neely said with a laugh.

Cassidy became the second-fastest Bruins coach to earn 100 wins (166 games) behind Tom Johnson (138 games). Cassidy replaced Bruins Stanley Cup-winning coach Claude Julien on Feb. 7, 2017.

“He’s done a very good job for us, obviously,” Neely said. “Coming in when he did and getting us to the playoffs and then almost having two, back-to-back 50-win seasons — pretty impressive. He learned from our playoff losses and how to maybe coach a little bit differently in the playoffs.

“It’s kind of a tale of two seasons. It’s to get into the playoffs, and once you’re in the playoffs, how do you adjust for a seven-game series? Butch has done a really good job of managing regular-season hockey and learning from playoff hockey.”

From a wider perspective, Sweeney was happy with the team’s entire coaching staff of Cassidy, Jay Pandolfo, Joe Sacco, Kevin Dean, Bob Essensa, J.P. Buckley and Kim Brandvold.

“I’m really proud of our group,” Sweeney said. “They had a lot of things thrown at them adversity-wise and they handled it really well. Certain times of the year you’re thinking it’s going to crack and go the other way and they get tighter and find a little bit of glue. Obviously, it comes from Bruce and the identity of how our team wants to play.”
