[4] As a child, Kuemper often played minor ice hockey alongside fellow Saskatoon natives Luke and Brayden Schenn.

[5] Kuemper's goaltending abilities first attracted attention when he played for the Saskatoon Contacts and Blazers in the Saskatchewan Male U18 AAA Hockey League (SMAAAHL) as an adolescent.

[6] During the 2005–06 SMAAAHL season, Kuemper, who split time in net for the Contacts with Carl Jahrus, had a 16-3 record and was third in the league with 2.32 goals against average (GAA).

[10] On December 13, 2007, Spokane traded Kuemper, who at that point was still playing with the Blazers, to the Red Deer Rebels in exchange for a conditional selection in the 2009 WHL Bantam Draft.

[18] Five days later, on February 17, Kuemper made 29 saves on 31 shots to earn his first career NHL win against the Detroit Red Wings.

[20] On May 7, Kuemper made his Stanley Cup playoff debut when he replaced Harding, who had suffered a left leg injury in the first period of a game against the Chicago Blackhawks.

[21][22] In the next season's playoffs, in 2014, Kuemper started in Game 3 of the Wild's Western Conference Quarter-finals matchup against the Colorado Avalanche, replacing Ilya Bryzgalov.

When the 2020 Stanley Cup playoffs were belatedly held in the summer in a bubble in Canada, Kuemper was widely considered the decisive factor in the Coyotes' victory over the Nashville Predators in the qualifying round.

[26] While the team performed well from the beginning of the season, Kuemper was considered somewhat shaky, and after an early injury caused him to miss time it raised questions about the stability of the Avalanche's goaltending.

It was announced that he would not play in Game 2, citing an unspecified upper body injury, with backup goaltender Pavel Francouz taking over again.

[35] Kuemper returned to the roster for Game 4 as backup to Francouz, where the Avalanche completed their sweep of the Oilers and advanced to the 2022 Stanley Cup Finals.

[38] Darcy Kuemper made the big saves in Game 4 and helped set up Nazem Kadri's memorable overtime winner.

In a series-deciding Game 6, Kuemper outdueled Lightning goaltender Andrei Vasilevskiy one final time and stopped 22 of 23 shots as the Avalanche won their third title in franchise history.

[39] In doing so, Kuemper joined hall of fame netminder Patrick Roy as the only other Avalanche goalie to start, play in, and win a Stanley Cup finals series.
