Under the direction of coach Peter Laviolette, the Capitals finished second in the East Division, posting a 36-15-5 record with 77 points, tied with the division champion Pittsburgh Penguins.
Washington is paced, as always, by captain Alex Ovechkin, who led the club with 24 goals in 45 games. The Caps also received plenty of offensive pop from scoring leader Nicklas Backstrom (53 points), blue liner John Carlson (44 points), and wingers T.J. Oshie (43 points) and Tom Wilson (33 points).
The Capitals finished fifth in the league in scoring (3.36 goals per game), boosted by their high-octane power play, which also ranked fifth at 84%. Boston's penalty kill should be a strong adversary, however, having finished second in the NHL this season at 86%.
"You never want to be undisciplined, especially in the playoffs," said McAvoy. "That doesn't really change. It's not really like anything would change. No one ever wants to be in the penalty box, no one ever wants to take stupid penalties. Having the onus on playing smart, no retaliatory stuff or unnecessary stuff.
"But obviously that's the game, stuff's gonna happen. We're gonna get penalties, but I know we have a lot of belief in our kill. I think we're up there as far as penalty kills go in the league. We trust that part of our game and we work really hard at it."
Six-foot-5 winger Anthony Mantha, acquired at the trade deadline from the Detroit Red Wings for Jakub Vrana, had four goals and four assists in 14 games and brought even more brawn and beef to an already heavy lineup. Wilson leads the way in that department, a fact that the Bruins know all too well after his hit on Brandon Carlo in March led to a seven-game suspension and left the B's blue liner with a concussion.
"He's not flying under the radar from our perspective, everyone knows what kind of player he is," Bruins president Cam Neely said of Wilson, who clashed with Trent Frederic all season and also dropped the gloves with Jarred Tinordi after the hit on Carlo. "He plays hard and he'll take the body. We have to expect that, I don't think that's going to change. We also need to focus on how we need to play and what we need to do to be successful. We have to be smart. More importantly, we've got to be careful with their power play. We've got to try to stay out of the box as much as possible."
Carlo, who missed nearly a month following the hit, is looking forward to a hard-hitting series.
"I think that feeds into the hands of our defensemen, as well," said Carlo. "We have some stable guys back there. I think the energy of the game, the pace of the game is brought up with playing a physical game. Personally, I enjoy it. I think we all do in this room. It makes for a fun series; it makes for a hard series. But this is the Stanley Cup Playoffs. You want it to be that way."
