In seven seasons with Sweeney as GM, the Bruins are 313-162-61 and have the third-best points percentage in the NHL (.641), since the 55-year-old replaced Peter Chiarelli on May 20, 2015.
"We are proud to extend Don Sweeney," CEO Charlie Jacobs said. "Under his management, the Boston Bruins have been one of the winningest franchises in the league and a perennial playoff contender year in and year out. While we recognize there is work to be done to achieve the ultimate goal of bringing the Stanley Cup back to Boston, I'm confident that Don's commitment to being best-in-class on and off the ice will help us climb that mountain once again."
The Bruins have qualified for the Stanley Cup Playoffs six straight seasons and reached the Stanley Cup Final in 2019, when they lost to the St. Louis Blues in seven games. Sweeney won the Jim Gregory General Manager of the Year Award that season, voted as the best GM in the NHL.
Boston lost to the Carolina Hurricanes in seven games in the Eastern Conference First Round this season, the first time it failed to win a playoff round since 2017. The Bruins finished 51-26-5 and were the first wild card into the playoffs from the East.
"Having had the pleasure of working closely with Don for more than a decade, I've seen firsthand his tireless work ethic when it comes to all facets of front office management," Bruins president Cam Neely said. "He remains committed to doing whatever it takes to give the Boston Bruins the best chance to win every season. I look forward to continuing to work with Don as we endeavor to bring another championship to this city and our fans."
Sweeney and the Bruins are searching for a coach to replace Bruce Cassidy, who was fired June 6. And the future of center Patrice Bergeron is unsettled, with the Boston captain eligible to become an unrestricted free agent July 13.
Several key players are expected to miss the start of next season after having surgery. Defenseman Charlie McAvoy (left shoulder) and top-line forward Brad Marchand (both hips) each is likely out until December. Defenseman Matt Grzelcyk (right shoulder) is slated to return in November.
"We're a competitive group and we're going to remain a competitive group," Sweeney said the day after Cassidy was fired. "Though we may need to infuse [younger players] at some point in time, if we have the injuries and things that catch up to you that you just can't get out from under, that's a problem.
"And Bergeron could be a direction shift as well."
