The line of David Krejci centering wings Milan Lucic and Jarome Iginla was particularly ineffective for Boston. Iginla scored a late goal with an extra attacker; the line combined for four shots on net and coach Claude Julien is urging those players to pick up their games, according to NHL.com.

"This is a line that's been hot and cold for us in the playoffs so far," Julien said. "David's shown a little bit of frustration, so he's got to battle thorough that stuff. It's a line that's given us a lot this year, so you have to have a little trust, and right now that's what I've got. Things have got to get better for that line for us to be successful."

The Canadiens have impressively grabbed the lead in this series without a goal from Gallagher or forwards Max Pacioretty or David Desharnais. Forward Dale Weise had the winning goal in Game 3 and defenseman P.K. Subban has three goals. Subban has been an uncontainable force against the Bruins, according to NHL.com.

"There's a lot of things I think I can do better," Subban said. "I'm [upset] they scored that second goal [in Game 3] and I'm on the ice for it. You're not always going to play a perfect game, but I look at the big picture. We got the win, that's the important thing
