And after the Bruins were eliminated in five games by the Tampa Bay Lightning in the Eastern Conference Second Round on Monday, the question seems suddenly more pressing.
"The reality is as every team gets a year older, there's an effect on the team," coach Bruce Cassidy said Wednesday. "For us, I think every summer [general manager Don Sweeney] would tell you, we sit down, go over our team, we're always trying to get bigger, faster, stronger, better. That's just the way it is.
"Does that mean moving out younger guys, older guys, middle-of-the-road guys? There's always that discussion."
The first question is whether or not defenseman Zdeno Chara will return to the Bruins. The 43-year-old captain, the oldest player in the NHL, can become an unrestricted free agent after the season. He signed a one-year contract in each of the past two seasons in March but did not do so this season. Chara said Thursday that he wants to continue playing for the Bruins, but has not yet had contract talks with Boston.
The other four members of the older core -- centers Patrice Bergeron, 35, and David Krejci, 34; goalie Tuukka Rask, 33; and forward Brad Marchand, 32 -- remain under contract for next season. Other key players, like 29-year-old defenseman Torey Krug, do not. The pending unrestricted free agent has become a significant part of the Bruins, including through runs to the Stanley Cup Final in 2013, when they they lost to the Chicago Blackhawks in six games, and 2019, when they lost to the St. Louis Blues in seven games.
Whether or not Krug and/or Chara return to the Bruins could go a long way toward shaping the way they look next season. After finishing ninth in the NHL this season with an average of 3.24 goals per game, Boston stumbled offensively in the postseason, scoring 2.23 goals per game, which ranks 18th. Cassidy cited two areas that will be crucial in improving that area: getting more shots through from the blue line and finishing once the puck arrives at the net.
The Bruins have some players emerging, including Charlie McAvoy, a 22-year-old who has taken over for Chara as the No. 1 defenseman. They have David Pastrnak, a 24-year-old forward who tied Alex Ovechkin of the Washington Capitals for the NHL lead in goals this season with 48, and who Cassidy said played the entire postseason with a lower-body injury. Forwards Jake DeBrusk, 23; Karson Kuhlman, 24; Jack Studnicka, 21; and Anders Bjork, 24, have shown promise.
