"I don't know what the odds were for us to win tonight, but we didn't give a (darn), to be honest with you," Landeskog said. "We just kept playing, and what a night. This is one heck of a group. I don't think I've ever been a part of a group with such team chemistry. Whether we made it or not, I'd still be really proud of this group. This is a big accomplishment to make it after such a tough season last year. We're not done."
The Avalanche made the playoffs for the first time since 2013-14 after finishing with an NHL-worst 48 points last season.
"It's got to be one of the best accomplishments in modern sports history," MacKinnon said. "We came in last by 20 points, we were the worst team in 25 years. We did the unthinkable. It's obviously a huge deal."
Jaden Schwartz and Brayden Schenn each had a goal and an assist, and Jake Allen made 34 saves for the Blues (44-32-6), who lost five of their final six games (1-4-1).
"There's a lot of people, a lot, I mean, majority of people who didn't even give us a chance to be in this game, to be here," Allen said. "We had our ups and downs this year, it was a wild year. But we rallied and found a way to beat good teams at the right time and give ourselves a chance.
"Credit to Colorado, they've improved immensely over the last couple of years and they played well again tonight, obviously. It's tough to take. We gave ourselves a chance, but it was still not good enough."

"He was very disappointed," Yeo said. "It was obviously a real tough loss to lose him two minutes into the hockey game."

They said it
"It just goes to show you what a group can do. When you believe in each other, when you believe in what we're trying to accomplish, and when you keep working towards that common goal, beautiful things can happen." -- Avalanche captain Gabriel Landeskog
"I was really proud of this team before tonight, and then to see them step up the way they did and finish the job of phase one of our season, I don't even know what to say." -- Avalanche coach Jared Bednar
"Right now, it is just tough to swallow, just an empty feeling. It's hard to dissect. We had our fair share of chances, 2-1 game, we hit two posts and a crossbar. We had (offensive) zone time, but they had some as well and obviously [Jake Allen] made some big saves to keep us in the game. It's just tough to dissect this." -- Blues forward Alexander Steen
