"I'm sure this term gets used by more than one person, but I know Patrick Roy said it to my dad (Claude Lemieux), and they tried to use it throughout their careers when they were winning, and it's, 'Never too high, never too low,'" Lemieux said. "And I think that that was one of those things. You know, we were playing well, and the score didn't reflect the way we were playing.
"So we just had to stay with it, not too high, not too low, not down because the score's down, or not up because the score is up, and I think tonight we emulated that."
Alexandar Georgiev made 38 saves for the Rangers (10-9-2), who lost 4-1 at the Ottawa Senators on Friday.
"It's just an unreal feeling that the guys kept at it, nobody gave up," Georgiev said. "It's rare that you get to come back from 4-0. It's a huge mental win."
Lehkonen and Max Domi each had two goals and an assist, Shea Weber scored, and Carey Price made 28 saves for Montreal (11-7-5), which has not won in its past four games (0-2-2).
"It's different than those three other games," Canadiens coach Claude Julien said. "You've got a 4-0 lead, you finally are scoring goals, but then you get sloppy. And I told the guys after the first period we were up 3-0 for one reason only, we capitalized on our chances, they didn't, because we didn't dominate the first period. [The Rangers] came to play tonight."
