MacKinnon gave the Avalanche their third lead of the game when he scored his first of the season with a one-timer on the power play at 9:50.
"It's only the third game through the year, but it felt like a lot more," said MacKinnon, who missed Colorado's first two games because of COVID-19 protocol. "It's always nice to get that zero gone. You can say all the right things, blah, blah, blah, but you want to score goals. I'd be lying saying it doesn't feel good to get the zero gone."
