"I think we got a lot of good movement going," he said of a Colorado attack that often swarmed the Calgary end, showing great puck control that kept the Flames on their heels for long stretches.
"There was a lot of assistance from our (defense). I thought that was the best game they've played in a long time - how active they were and how involved they were all over the ice. There was a lot of fun."
MacKinnon's 26:26 ice time was the game-high among forwards, only Flames defenseman Mark Giordano (28:55) and Avalanche defenseman Tyson Barrie (28:13) saw more action.
It was MacKinnon's second consecutive industrial-strength night of work, having played 25:04 in Game 1, and he can expect pretty much the same moving forward.
"I think that's what I'm going to play," he said with a grin. "That's a lot. Twenty-five is a lot for sure, but whenever (Bednar) says to go, I'm going to go."
Avalanche captain Gabriel Landeskog, who played a healthy 25:54, had a good look at MacKinnon's winner.
"It's a good feeling. There's nothing like … Stanley Cup overtime," he said. "I've said it before: Nate's a superstar and that's what superstars do."
The winning goal doesn't happen without Grubauer's save on Frolik.
"It's a great stop by (Grubauer)," Landeskog said. "It's a bang-bang play coming from behind the net. Grubby finds a way. I think he gets a glove on it and it turns the other way. Nate was skating like it was the first period, first shift. That's the kind of speed he's got and he's in great shape. Mikko makes a nice play to him. That's what good players do."
It was a happy and relieved Avalanche team that returns to Denver on Sunday, having worked overtime to even the series.
"That's the least we came here for," Landeskog said. "We would've liked to win both games, but a 1-1 split, we'll take that. Now it's a matter of us coming home and repeating this effort."
