Junior Makar, a
Calgary native, first played within the Crowchild Blackhawks minor-hockey program before moving to play with the Northwest Calgary Athletic Association (NWCAA) Bruins at the
Bantam level in 2011. He also played bantam with the Calgary Flames before moving to minor midget with the NWCAA Stampeders. Makar was originally drafted at the
major junior level by the
Western Hockey League (WHL)'s
Medicine Hat Tigers in the eighth round, 164th overall, of the 2013 WHL Bantam Draft. Having returned to the Calgary Flames for the minor midget level, in his only full season with the club in 2014–15, Makar led the team in scoring with 23 points in 34 league games, being named the team's Most Valuable Player and selected to the
Alberta Midget Hockey League First All-Star Team. To retain his
NCAA eligibility, Makar joined as an affiliate player to the
Brooks Bandits of the
Alberta Junior Hockey League (AJHL) at the tail end of the season, recording five points in three regular season games. In helping the Bandits reach the finals, Makar was third among defenceman in scoring with 7 points in 20 games. Having agreed to return with the Bandits in the forthcoming seasons, Makar announced his commitment to play collegiate hockey with the
University of Massachusetts Amherst of the
Hockey East NCAA conference on August 29, 2015. As a 17-year-old, Makar established himself as a standout defenceman with the Bandits in 2015–16, logging 55 points in 54 games, en route to earning AJHL All-League and All-Rookie recognition. He scored 14 points in 13 games to help the Bandits claim the AJHL championship. His productive season collected AJHL and CJHL Rookie of the Year Awards, the Western Canada Cup Top Defenceman Award, and the RBC Cup Top Defenceman, Top Scorer and Most Valuable Player awards. Makar sustained and built upon his previous success in the 2016–17 season to lead all defencemen and finished sixth among all skaters in the AJHL with 75 points (24 goals and 51 assists) in 54 games, collecting the league's MVP and top defenceman accolades. He had 16 points in 13 playoff games to help Brooks to a second straight AJHL championship and six points in five games to help the Bandits to a second-place finish in the
Royal Bank Cup. He was chosen as the RBC Cup Top Defenceman and Most Valuable Player, the first player to ever be named RBC Cup MVP in back-to-back seasons. He received the CJHL Most Valuable Player Award and won the prestigious RBC National Junior A Player of the Year Award. at the
2017 NHL entry draft. Through Makar's rapid rise up the rankings before the
2017 NHL entry draft, he was considered a top prospect and one of the top defencemen available. He was described as a dynamic skater that creates offence whenever he is on the ice. Makar was ultimately selected fourth overall by the
Colorado Avalanche, the second defenceman selected in the draft, after third overall selection
Miro Heiskanen. Makar became the highest-drafted player to come straight from the AJHL, and just the second in the first round since
Joe Colborne in
2008.
College Despite his blue-chip prospect status, Makar opted to remain loyal to his commitment to joining the rebuilding UMass Minuteman program for the
2017–18 season. As a freshman, he immediately assumed a top-pairing role, alongside Jake McLaughlin, and recorded his first collegiate point in his debut against
Arizona State University on October 6, 2017. He recorded his first goal in a 4–0 victory over
Merrimack College on October 27, 2017. While showing an adjustment period to the collegiate level, Makar raised his game through the new year to help the Minutemen to turnaround their program to make the postseason before suffering a 7–2 defeat to the hands of
Northeastern University. He finished fifth on the team in scoring, second amongst defenceman, with 5 goals and 16 assists for 21 points in 34 games. He was selected with co-Rookie of the Year honors by the New England Hockey Writers Association and by finishing ninth in defenceman scoring in the
Hockey East, he was selected to the conference's All-Rookie and Third All-Star Teams. With the season concluded and despite interest from the Colorado Avalanche in turning pro, Makar opted to continue his development in returning for his sophomore season with UMass in
2018–19. That season, Makar became the first Minutemen honored as
Hockey East Player of the Year after he led the league in scoring and finished second in the conference. Makar was also selected for the
Hockey East First All-Star Team and named a
Hobey Baker Award finalist. On April 12, Makar was announced the winner of the Hobey Baker. The following night, Makar and the Minutemen lost 3–0 to
University of Minnesota Duluth in the
Frozen Four final.
Professional Debut and Calder Trophy (2019–2021) On April 14, 2019, the Avalanche signed Makar to a three-year, entry-level contract. He scored his first career NHL goal with his first shot in the league in his debut a day later, during game 3 of the first round of the
2019 Stanley Cup playoffs against the
Calgary Flames. In so doing, he became the first defenceman to score a playoff goal in his NHL debut. Makar made the Avalanche opening lineup for the
2019–20 season and he scored his first career regular season goal in a 6–1 win over the
Vegas Golden Knights. He was subsequently named a Third Star of the Week for the week of November 10, becoming the first Avalanche rookie to earn the honor. On November 12, 2019, in a 4–0 road win against the
Winnipeg Jets, Makar became the second Avalanche defenceman to record 18 points in 18 games as a rookie. However, he suffered an upper-body injury in a game against the
Boston Bruins on December 7 and was listed as day-to-day. At the time of his injury, he was leading rookies in scoring with 28 points in 29 games. Makar returned to the Avalanche's lineup on December 27, where he recorded an assist in the 6–4 loss to the
Minnesota Wild. On January 18, 2020, Makar set a new Avalanche franchise record with his 11th goal of the season, besting
John-Michael Liles record for most goals by a rookie defenceman. As a result of his play, he was named a
Calder Memorial Trophy finalist alongside
Quinn Hughes and
Dominik Kubalík. During the second round of the NHL playoffs, Makar surpassed the record for most points in a postseason by a rookie defenceman, before it was beaten by Hughes the following night. Following the conclusion of the regular season, Makar was awarded the Calder Memorial Trophy as the rookie of the year. After the 2020–21 season, Makar was named a finalist for the
James Norris Memorial Trophy and finished second in the voting for the trophy.
Stanley Cup, Norris and Conn Smythe trophies (2021–present) On July 24, 2021, Makar signed a six-year, $54 million extension with the Avalanche. On October 28, Makar scored two points (one goal and one assist) in a 4–3 win against the
St. Louis Blues, in doing so, he scored his 100th point in just 108 games, which tied him with
Sergei Zubov as the sixth-fastest defenceman to accomplish this feat. On March 25, 2022, Makar scored his 24th goal of the 2021–22 season in a 6–3 win against the
Philadelphia Flyers, breaking the Avalanche's single-season record for goals scored by a defenceman. He finished the season with 28 goals, the most by a defenceman in the NHL since
Brent Burns in the
2016–17 season, and 58 assists. 19 of his 28 goals were at even strength. Makar was named a James Norris Memorial Trophy finalist for the second consecutive season. He won the Norris Trophy, the first Avalanche defenceman to do so, and finished eighth in voting for the
Hart Memorial Trophy, awarded by the
Professional Hockey Writers' Association to the league's
most valuable player. The Avalanche finished first in the
Western Conference, and second in the league overall, advancing into the
2022 Stanley Cup playoffs to meet the
Nashville Predators in the first round. Makar scored 10 points in a four-game sweep of the Predators, setting a record for points by a defenceman in the first four games of a postseason. Teammate
Nathan MacKinnon remarked, "he might be the best player in the league right now." He would amass a further 19 points in the next three rounds, as the Avalanche ousted the Blues and the
Edmonton Oilers before defeating the two-time and defending champion
Tampa Bay Lightning in the
2022 Stanley Cup Final. Makar finished the playoffs with a team-leading 29 points, the fourth-most for a defenceman in a single postseason in league history. He was awarded the
Conn Smythe Trophy as the most valuable player in the postseason, and became only the third defenceman to win the Norris and Conn Smythe Trophies in the same season, after
Bobby Orr (
1970 and
1972) and
Nicklas Lidström (
2002). Makar recorded 20 points in the first 17 games of the
2022–23 season, his 20th being a power play goal scored in a November 21, 2022, game against the
Dallas Stars. This was his 200th career point in 195 games, the fastest pace of any NHL defenceman to that milestone. Previous record holder
Sergei Zubov reached the mark in 207 games. He attracted notice when, during a December 19 game against the
New York Islanders, he convinced the referee to rescind a tripping penalty that had been incorrectly assessed against Islanders forward
Mathew Barzal, with Makar clarifying that he had fallen on his own rather than being tripped. Barzal remarked that it was "obviously, good sportsmanship on his part. I don't know if I would have done the same, to be honest with you." Injuries caused Makar to miss 22 games in the regular season, but he finished with 17 goals and 49 assists in 60 games, and was named a Norris Trophy finalist for the third consecutive year. during game four of the
2023 Stanley Cup playoffs. During game four of the first round of the
2023 Stanley Cup playoffs, Makar was involved in a controversial on-ice incident after delivering what many deemed to be a hard, late hit into the boards on
Seattle Kraken forward
Jared McCann. Although the play had not officially been whistled dead, the puck had been deflected into the upper safety netting and McCann had slowed his pace in anticipation of a whistle when Makar delivered the hit. The officials initially appeared to assess Makar for a five-minute major penalty; he ultimately received a two-minute interference call. McCann, who was ruled out for game five, was injured as a result of the hit and did not return for the rest of the game, which was ultimately a 3–2 overtime victory for the Kraken. After the game, Makar stated that he had not intended to injure McCann and that he was unsure if the puck was still in play at the time. The next day, Makar received a one-game suspension for the hit on McCann; this was the first suspension (and first disciplinary offense) of Makar's NHL career. Makar returned for the remainder of the series, which saw the Avalanche upset by the Kraken in seven games. On March 6, 2024, Makar recorded his first career NHL
hat trick in a 7–2 victory over the
Detroit Red Wings; becoming the first Avalanche defenceman to do so since
Sandis Ozoliņš back on December 6, 1999. He was voted a Norris Trophy finalist for the fourth consecutive season, having finished second in points and first in points-per-game among defencemen. The following
2024–25 season would see Makar reach new offensive achievements. On April 3, 2025, he recorded his 30th goal of the season, becoming the ninth defenceman in NHL history to reach that mark, and only second in the post-
lockout era. He finished the season with 92 points, ninth in league scoring overall. In addition to being a Norris Trophy finalist for the fifth time, he was for the first time a finalist for the
Ted Lindsay Award, awarded by the
National Hockey League Players' Association to the "most outstanding" player in the NHL. Makar was subsequently awarded his second career Norris Trophy on June 11, 2025, receiving 176 of 191 first-place votes. During a March 18, 2026, game against the Dallas Stars, Makar scored his 20th goal of the
2025–26 NHL season, becoming the first defenceman since
Phil Housley to score 20 goals in three straight seasons. He scored the 500th point of his career when he assisted on a
Brock Nelson goal in a 4–2 loss against the Winnipeg Jets on March 28. ==International play==
