Normally those that follow the Bruins expect their special teams to be more drag than strength at Stanley Cup Finals time of year, but that’s far from the case this season. The Bruins power play is 2-for-9 in three games against Chicago, and that solid 22 percent success rate is light years ahead of their work two years ago during the short, unproductive Tomas Kaberle Era. But the penalty kill is where it’s at for the Black and Gold. The Bruins have killed off 27 straight opposition power plays, dating back to May 25 in Game 5 against the New York Rangers in the second round of the playoffs. They held Pittsburgh 0-for-15 in the Eastern Conference Finals, and have killed the first 11 power plays awarded to the Blackhawks in their current series. “We know [Chicago has] got some great players,” said coach Claude Julien. "Our penalty kill has to be at its best. It really got better as the playoffs went on. But we really picked it up against Pittsburgh for the same reasons, same kind of a dangerous power play. "It just continues to give us some help in these games. Obviously we don't want that to be a momentum changer against us. [And] I think killing those has really given our bench a boost. We just keep plugging away with those special teams, but at the same time, I'm not going to change my attitude as far as saying that 5-on-5 right now is just as important. So we got to continue to play well 5-on-5.” There was some concern about the after-effects of Gregory Campbell’s injury on the penalty kill, and if his absence would really take away from what’s essentially been the same combos of players for the last three years. Campbell and Daniel Paille have been linemates and penalty killing partners for as long as they’ve been together as Bruins.
