So the Vegas Golden Knights won, right?
Wrong.
The Avalanche won, anyway.
They won 3-2 in overtime in Denver on Wednesday and took a 2-0 lead in the Stanley Cup Second Round, thanks to a power-play goal by Rantanen at 2:07 of overtime, 39 saves by Philipp Grubauer and a little help from Grubauer's goal posts.
That should concern the Golden Knights, who were far better than they were in a 7-1 loss in Game 1 but must be even better in Game 3 in Las Vegas on Friday (10 p.m. ET; NBCSN, CBC, SN, TVAS).
And that should scare the rest of the NHL, as if anyone wasn't frightened already.
The Avalanche are on a six-game winning streak to open the Stanley Cup Playoffs. They can dominate you, as they showed by winning each of their first five games by three goals or more, and they can eke one out too, as they showed Wednesday.
"If I look at the two games we played [against Vegas], the first one we played really well and then not our best game but still find a way," Rantanen said. "That's what we've been doing the whole year. Sometimes we haven't been feeling it, and [Grubauer has] been playing awesome and stealing some wins for us like today. But that's what you need if you want to win the Cup."
To appreciate how deep this team is, consider that when Brandon Saad gave Colorado a 1-0 lead in the first period, he stretched his goal-scoring streak to five games. The Avalanche have the likes of MacKinnon, Rantanen, Landeskog and Makar, and they still have a forward who won the Stanley Cup twice, with the Chicago Blackhawks in 2013 and 2015, and can produce like this.
Also consider that Colorado had four power plays in the first period, and it was not the first unit but the second unit that cashed in to make it 2-1. Forward Tyson Jost scored his second of the playoffs. Again, that's depth.
"I liked our first period," coach Jared Bednar said. "We were skating, drawing penalties, winning a lot of races, winning a lot of puck battles. And in the final 40 minutes, we didn't do that."
The Golden Knights took over in the second and third. They didn't allow the Avalanche's offensive stars time and space. They blocked shots. They won battles and generated scoring chances.
But they never took the lead thanks to Grubauer and his goal posts.
Grubauer, a finalist for the Vezina Trophy this season, got a piece of a Jonathan Marchessault shot late in the second, just enough that the puck went off the post.
Early in the third, Reilly Smith hit a post, and then Grubauer stopped a Max Pacioretty rush chance. Later in the third, Grubauer stopped Alex Tuch all alone in front.
