When the Caps downed the Bruins in Beantown just over three weeks ago, they also halted a five-game Boston winning streak. Beginning with that loss to the Caps on Jan. 10, the Bruins have won only two of their last eight games (2-3-3).
Like the Capitals, the Bruins are hanging in the chase for the eight postseason berths from the Eastern Conference.
Boston's top forward line of Brad Marchand, Patrice Bergeron and David Pastrnak is one of the league's top units, and that trio has been the foundation of the Boston attack for the last three seasons. Pastrnak has reached the 30-goal plateau for each of those three seasons - including the current one - and Marchand is aiming for his fourth straight season with 30 or more goals in 2018-19. Bergeron will play in his 999th career NHL game on Sunday against the Caps. Arguably the game's top two-way pivot, Bergeron has four career 30-goal seasons in his 15 campaigns in the league.
All three players are Boston drafted and developed, and all three have spent the entirety of their careers in a Bruins sweater. As the trade deadline approaches, the B's will be likely be looking to augment and diversify their attack. As currently constituted, the Bruins are probably too dependent upon the Bergeron line for offense. Boston scored 38 goals in January, and the Bergeron line accounted for 18 of them (47.4 percent). On the season, that trio has combined for 65 of Boston's 147 goals (44.2 percent).
Having just faced Calgary's torrid top line on Friday may help the Caps as they take on the Bruins on Sunday. The two teams are similarly constructed in some ways.
"Yeah, I think it helps," says Caps goaltender Braden Holtby. "They are similar in a lot of ways. What makes Calgary good - their top line is obviously very skilled and very good - is their defense kind of runs their team. They're very mobile, very good at getting pucks through and smart in that way.
"When you couple that especially with their top line, you get a dangerous five-man attack. And that's very similar to Boston where you have [Charlie] McAvoy and [Torey] Krug and those guys. They're mobile, they're smart, and they play well with those top skill players. So they do have a lot of similarities."
