Mikko Rantanen scored a hat trick, and Nathan MacKinnon, Cale Makar and Samuel Girard each had two assists for Colorado. Alexandar Georgiev allowed five goals on 16 shots before he was replaced by Justus Annunen, who allowed two goals on four shots.
“No question, the biggest issue was rush coverage and getting beat back up the ice on a couple of goals,” Colorado coach Jared Bednar said. “They scored four goals on the rush. … The number of scoring chances we gave up was not an issue. We did some good things throughout the course of the game. Every time we got ourselves back in the game, we made another mistake. And every mistake we made ended up in the back of our net.”
It was the season opener for each team.
Rantanen gave the Avalanche a 1-0 lead at 10:48 of the first period with a one-timer from above the left circle.
Olofsson tied it 1-1 just 27 seconds later when his wrist shot from a tight angle below the left circle beat Georgiev near side.
“I saw him cheating a little bit. I saw [Nicolas Roy] in front of the net, battling, and I thought the goalie was expecting a pass,” Olofsson said. “So I just tried to hit the net, and it went in.”
Barbashev put Vegas ahead 2-1 at 18:32 with a snap shot from the right circle.
Stone pushed it to 3-1 just 25 seconds later, finishing off a 2-on-1 rush with Eichel.
