In the end it did not matter, as Lundqvist and the defense stood tall over the final 20 minutes in limiting the Canadiens to just six shots on goal before Grabner's empty-netter with 1:10 remaining iced in the visitor's favor.
New York clinched its playoff berth on March 28 in San Jose, and have spent the last three weeks fine-tuning their games in preparation for tonight while also utilizing that time to rest several players.
Lundqvist said it's easier said than done to get back to a high-level of play, but that he and his teammates were able to do that in Game 1.
"It's not easy to go out in your first game and execute," Lundqvist admitted. "We did and started off on the right foot."
The road victory in Game 1 is crucial, but that's all it is: one game.
A core group of these Rangers have been to two Eastern Conference Finals and a Stanley Cup Final since 2012, and know the series is long from over despite the early advantage.
"You enjoy it tonight but it means nothing tomorrow," said Derek Stepan. "It's a race to four and the only one that really matters is that fourth one. Our group is real happy with the way Game 1 went, but again, we're looking towards Game 2."
