Three years ago, Pastrnak was well on his way to his first 50-goal season, just two shy with 12 games to play. Nothing, it appeared, would stand in his way so long as he stayed healthy.
But then, the unthinkable happened. With the COVID-19 pandemic wreaking havoc across the world, the NHL shut down the 2019-20 regular season, cutting short Pastrnak's chase for 50.
It was that experience that made Sunday's achievement that much more meaningful.
"It's pretty special. It's even better with the win," said Pastrnak, who also registered the 600th point of his NHL career and a new single-season high in points (96) when he beat Freddie Andersen on a breakaway at 4:43 of the first period to put Boston up, 1-0.
"I came close a couple years ago. You never know what can happen. I had plenty of games to get there and, all of a sudden, Covid happened. It's definitely special. It's been a long way and obviously big thanks to all my teammates and my family. It's pretty cool. Even better to share it with the guys that I have here."
The play began with McAvoy collecting a loose puck in front of the Bruins' net and sending an outlet pass to Pastrnak in the neutral zone.
"I'm happy to be in the record books as a part of it," said McAvoy. "First 50-goal season. I'm so happy for him. He deserves it, he works very hard. He's an unbelievable hockey player…it's amazing.
"He puts himself in some very good company. He means so much to all of us on a personal level and then he's the hockey player that he is for the Boston Bruins. I'm so happy for him and what an accomplishment it is. It's very well deserved."
Pastrnak finished off the tally with some help from Carolina blue liner Brent Burns, who hustled to catch up to the B's winger on the backcheck, but inadvertently assisted on the marker when his stickcheck caused Pastrnak to lose the puck, which then trickled through Andersen's five-hole.
"That's how the game works. You have a couple chances [Saturday] night to get there, a couple breakaways and good chances that I wouldn't change much," said Pastrnak. "But it didn't go in last night. Today, you kind of lose the puck and it goes in. That's the game. I obviously take it…I'm not [Nikita Kucherov], I don't know how to do that on purpose."
