Makar finished second among NHL rookies in scoring during the 2019-20 season with 50 points (12g/38a) in 57 games. His 0.88 points-per-game average led all first-year players and tied for the third-highest total by a rookie defenseman in NHL history (min. 50 GP). Only Leetch (1.04, New York Rangers, 1988-89) and Murphy (0.95, Los Angeles Kings, 1980-81) averaged more.
The right-shot defenseman led all rookie blueliners with 12 goals that year and tied for first among all rookies with four game-winning tallies. Makar's 38 assists ranked second among first-year skaters and he was first among rookie blueliners in even-strength goals (eight) and points (31) as well as power-play goals (four). Makar led Colorado's blueline in points, goals and assists, all franchise records for a rookie defenseman. His four game-winning tallies were also a new franchise mark for a first-year backliner.
Makar went on to record 15 points (4g/11a) in 15 contests during the 2020 Stanley Cup Playoffs. His 15 points were the second most ever by an NHL rookie defenseman in a single postseason, trailing only Quinn Hughes' 16 points (2g/14a) in 17 contests that same year. Makar led all rookies that postseason in points-per-game (1.00) and plus/minus (+12), while ranking second in assists and third in both points and goals (tied). He was just the fifth rookie ever-and the only defenseman on that list-to average at least a point-per-game during a single playoff year (min 15 GP), joining forwards Don Maloney (1979, New York Rangers), Dino Ciccarelli (1981, Minnesota), Marian Stastny (1982, Quebec) and Ville Leino (2010, Philadelphia).
Selected by Colorado in the first round (fourth overall) of the 2017 NHL Draft, Makar spent two seasons at the University of Massachusetts, where as a sophomore in 2018-19 he became the first player in school history to win the Hobey Baker Award. He led the Minutemen to their first-ever No. 1 ranking that year and eventually a spot in the 2019 NCAA Frozen Four Championship Game.
Seventy-two hours after winning the Hobey Baker and 48 hours after playing in the NCAA title game, Makar scored his first NHL goal on his first shot in the opening period of Colorado's Game 3 victory against Calgary in Round 1 on April 15, 2019. He became the first defenseman in history to score his first career goal while making his NHL debut in the Stanley Cup Playoffs. Despite playing just 10 games, Makar ended up leading all NHL rookie defensemen with six points (1g/5a) during the 2019 postseason.
