Editing Boston Bruins (section)

===Don Sweeney era (2015–present)===
On April 15, 2015, Peter Chiarelli was fired by the Boston Bruins. On May 20, the Bruins named former player [[Don Sweeney]] as the team's new general manager for the [[2015–16 NHL season|2015–16 season]]. One recent all-time franchise achievement the Bruins attained in the 2015–16 season is shared by only their greatest rival, the Canadiens – a total of 3,000 wins in the team's existence, achieved by the Bruins on January 8, 2016, in a 4–1 road victory against the New Jersey Devils.<ref>{{cite web |url=https://www.nhl.com/gamecenter/bos-vs-njd/2016/01/08/2015020608 |title=Bruins defeat Devils for 3,000th win in history |last1=Morreale |first1=Mike G. |date=January 8, 2016 |publisher=National Hockey League |access-date=January 9, 2016 |quote=Center Ryan Spooner and defenseman Colin Miller each had a goal and an assist to help the Boston Bruins become the second team in NHL history to win 3,000 regular season games with a 4–1 win against the New Jersey Devils at Prudential Center on Friday. |archive-date=January 9, 2016 |archive-url=https://web.archive.org/web/20160109090212/http://www.nhl.com/gamecenter/en/recap?id=2015020608 |url-status=live}}</ref> The team was seen as a playoff contender throughout the regular season. However, a sub-.500 record on home ice and frequent road losses in the final two months of the regular season resulted in a three-way battle for the final playoff spot in the Eastern Conference. The Bruins had a chance to clinch the final playoff berth with a win over the Ottawa Senators on the second-to-last day of the season, but they lost the game and that combined with a Flyers' win over the Penguins, knocked them out of playoff contention in favor of the Flyers. For the first time since the two seasons following the 2004–05 lockout, the Bruins did not qualify for the playoffs in two consecutive seasons.

During the last two months of the [[2016–17 NHL season|2016–17]] regular season, the Bruins fired head coach Claude Julien and promoted [[Bruce Cassidy]] to interim coach.

Cassidy returned as head coach for the [[2017–18 NHL season|2017–18 season]], leading the Bruins to the playoffs a consecutive season.
