Rust had three goals and an assist, Rakell had two goals and two assists, and Sidney Crosby had three assists as Pittsburgh’s top line combined for 11 points.
“They do feel nice, but obviously at the end of the day it is just one game,” Rust said about the lopsided result. “But it is nice for everybody’s confidence to see a lot of pucks go in the net.”
Kris Letang had a goal and an assist, Matt Grzelcyk had two assists, and Tristan Jarry made 21 saves for the Penguins (13-14-4), who have won six of their past eight games.
“I think as a team, you still have to develop all those different things that come with winning and being consistent,” Crosby said. “And we’ve been doing it lately, and it’s something that we’ve been building on. So, that’s something that needs to continue. It’s a process, it doesn’t happen overnight, but we’re giving ourselves a chance and it’s way more fun to play when it’s that way.”
Nick Suzuki and Joel Armia scored for Montreal (11-15-3), which allowed six goals in the third period.
“I’m still trying to think about what just happened,” Suzuki said. “I don’t know who that was out there, and it was embarrassing by us.”
Sam Montembeault allowed six goals on 26 shots before he was replaced by Cayden Primeau at 8:41 of the third period, who allowed three goals on seven shots in relief.
“I think every play matters in this League,” Canadiens coach Martin St. Louis said. “There’s not one action on the ice that can’t affect the outcome of the game, and those actions got away from us in the third.”
Suzuki gave the Canadiens a 1-0 lead at 2:12 of the first period. He went forehand to backhand around Jarry to finish off a 2-on-1 rush with Cole Caufield, who carried the puck into the offensive zone after cutting off Letang’s cross-ice pass inside Montreal’s blue line.
Rakell tied it 1-1 with a power-play goal at 4:18. He redirected Letang’s centering pass from the left corner under Montembeault’s left pad from the edge of the crease.
