But to MacKinnon, the highlight might as well be in black and white.
"Honestly," he said, "it feels like another lifetime ago."

Looking back, that outdoor game wasn't as satisfying as one the Avalanche will play against the Los Angeles Kings in the 2020 Navy Federal Credit Union Stadium Series at the U.S. Air Force Academy's Falcon Stadium on Saturday (8 p.m. ET; NBC, SN360, TVAS, AFN|sports2).
"It's cool to be on a really good team and kind of earn this game, not just because of what the guys did in 2001," MacKinnon said.
That game at Coors Field felt more about the past than the present. The matchup recalled the Colorado-Detroit rivalry of the late 1990s and early 2000s, when the Avalanche won the Stanley Cup in 1996 and 2001 and Detroit won it in 1997, 1998 and 2002. The alumni stole the spotlight.
The Avalanche entered that game holding the second wild card into the Stanley Cup Playoffs from the Western Conference. They lost 5-3 and ended up missing the playoffs.
"We kind of had a bad year," MacKinnon said.
It got worse the next season, when the Avalanche finished last in the NHL with 48 points, the lowest total in a full season since the League introduced the salary cap in 2005-06.
But they made the playoffs in 2017-18, losing to the Nashville Predators in six games in the Western Conference First Round, and made the playoffs last season, defeating the Calgary Flames in five games in the first round before losing to the San Jose Sharks in the second.
