The Boston Bruins have announced tonight that they have relieved Bruce Cassidy of his duties as head coach. Cassidy had been the Bruins’ head coach since 2017-18 and led the team to the playoffs in each season he coached, including a run to Game Seven of the Stanley Cup Final in 2019. Bruins GM Don Sweeney issued the following statement as part of the announcement:

Today I informed Bruce Cassidy that I was making a head coaching change. After 14 years working with Bruce, this was an extremely difficult decision. I want to thank and acknowledge Bruce for all his work and success with the Bruins organization. His head coaching record for the Bruins is impressive, and we are appreciative of Bruce both professionally and personally. After taking some time to fully digest everything, I felt that the direction of our team for both this season and beyond would benefit from a new voice. I want to wish Bruce, Julie, Shannon and Cole much success as a family and with their future opportunities.

This move is a genuinely surprising one, although there have been some hints of simmering unhappiness in the Bruins’ organization that may not have been seen by observers outside of the Boston market. The Athletic’s Fluto Shinzawa covered the disconnect on offensive philosophy between Cassidy and Sweeney, and further reported that the team’s management had turned up the heat on Cassidy. While at the time some may have looked at Shinzawa’s reports and seen the normal, expected reaction of a team reeling from a difficult playoff exit and not any indication of any looming changes, it’s now clear that his work was foreshadowing the major change that was just announced.
