Part of the Boston Bruins' success over the past few seasons can be attributed to their strong defense, a unit that features veterans Zdeno Chara and Torey Krug. When the NHL was suspended last month due to the coronavirus pandemic, Boston ranked first in the league with only 2.39 goals allowed per game.
However, the Bruins could undergo some defensive changes as soon as next season. Chara is 43 and likely nearing the end of his career, while Krug is set to become an unrestricted free agent this summer.
One obstacle that Boston may have to overcome in order to bring back Krug is the uncertain salary-cap situation.
