The Bruins were a top NHL team over the past 10 to 12 seasons next to the Chicago Blackhawks, Los Angeles Kings, Pittsburgh Penguins, and Tampa Bay Lightning. The 2011 Boston Bruins that won the Stanley Cup rank as a top 5 team from the 2010s, in my books. The B's also made the Finals in both 2014 and 2019, a lot more than most NHL teams can say.
With core players from those teams like Zdeno Chara and Tuukka Rask gone and at least one more season of Patrice Bergeron and David Krejci's, there are rumours of a rebuild in the near future for the club.
General manager, Don Sweeney's number one priority has to be a Pastrnak extension. He's still young and a very important piece to the Bruins current, and hopefully, future core.
Players the Bruins could be willing to move are Mike Reilly, Matthew Grzelcyk, Derek Forbort, Nick Foligno, Tomas Nosek and possibly Craig Smith or Linus Ullmark. Boston will only have around $5 million in cap space as of now.
