But not only did they fight back to make the Stanley Cup Playoffs, they won the Central Division.
They are a threat to repeat entering Game 1 of the Western Conference First Round against the Seattle Kraken at Ball Arena on Tuesday (10 p.m. ET; ESPN, SN360, TVAS, ALT, ROOT-NW).
"We had the option of kind of, you know, saying, 'Aw, we won the Cup last year. Whatever. Let's just chalk it up and go on to next season,'" center Nathan MacKinnon said. "But we dug in.
"It's definitely the most resilient team I've been on, for sure, just the way we battled to win the division. It's really impressive."

Go back to Jan. 12, when the Avalanche played the Chicago Blackhawks, who were last in the NHL entering the game. Colorado lost 3-2 and fell to 1-6-1 in eight games.
"That was a tough one, because it felt like we actually played hard that game and still lost," MacKinnon said. "So that's when you start to really question things."
The Avalanche were 14 points behind the Dallas Stars for the Central Division lead and four points behind the Edmonton Oilers for the second wild card into the playoffs from the Western Conference.
"Everybody kind of little bit counted us out maybe in January, and there was some hesitation even our minds," forward Mikko Rantanen said. "But we found a way, and 'determination' is one good word to describe us."
The Avalanche went 31-8-4 the rest of the way, including 7-0-1 in their final eight games to win the Central. They had a .767 points percentage after Jan. 12, third in the League behind the Boston Bruins (.798) and the Oilers (.795).
MacKinnon had 72 points (31 goals, 41 assists) in 43 games in that span, second to Edmonton Oilers center Connor McDavid, who had 74 points (29 goals, 45 assists) in 39 games. Rantanen had 55 points (28 goals, 27 assists) in 43 games in that span, tied for fifth in the NHL.
To clinch the division, the Avalanche needed to defeat the Nashville Predators on Friday in the last game on the NHL schedule. After the Avalanche blew a 3-1 lead playing on the road in their second game in two nights and third in four, MacKinnon scored with 1:42 to go to win it 4-3, giving him four points (three goals, one assist).
"He's a competitor," coach Jared Bednar said. "Deep down, that's what it is. I mean, no better example than the other night in Nashville.
"We looked a little bit tired. We did some really good things early, put the puck in the net. They created a couple chances, made it even, and he just took over the game, for me. He ends up winning it for us on a hat-trick goal. He just wasn't going to be denied."
