In his first full WHL season in 2016–17, he appeared in 63 games for Lethbridge, scoring nine goals and 24 assists for 33 points.[7] The Hurricanes finished first in their division and returned to the WHL playoffs for the first time since 2009.[8] He played in 13 playoff games, adding two assists as Lethbridge was eliminated in the conference finals.[6][7]
In his second season with the Hurricanes in 2017–18, he led the team's defencemen in scoring and third overall, with 11 goals and 65 points in 68 games.[6][7] The Hurricanes advanced to the conference finals in the 2018 playoffs, but were eliminated again in the series.[9] Addison added seven goals and 19 points in Lethbridge's 16 playoff games.[6][7] He returned to Lethbridge for a third season in 2018–19 in which he scored the identical number of goals, assists and points as the previous season, in 67 games.[7] However, despite making the 2019 playoffs, the Hurricanes were knocked out in the opening round.[10] In seven playoff games, he scored two goals and nine points.[7] In his final season of junior in the 2019–20 season, he played 50 games with Lethbridge, scoring ten goals and 52 points before the season was cancelled due to the COVID-19 pandemic on March 18, 2020.[7][11] Addison was named a WHL Eastern Conference First Team All-Star for the 2019–20 season.[12]
Professional
Addison was selected by the Pittsburgh Penguins of the National Hockey League in the second round, 53rd overall, in the 2018 NHL entry draft. He was signed by the Penguins to a three-year, entry-level contract on April 7, 2019.[13] After his junior team was eliminated in the 2019 WHL playoffs, Addison joined Pittsburgh's American Hockey League (AHL) affiliate, the Wilkes-Barre/Scranton Penguins on an amateur tryout contract on April 19, 2019.[14] He played in three games with Wilkes-Barre/Scranton, registering two assists.[7]
Addison was traded by the Penguins along with forward Alex Galchenyuk and a conditional first-round pick in the 2020 NHL entry draft to the Minnesota Wild in exchange for forward Jason Zucker on February 10, 2020.[15][16] To begin the pandemic-delayed 2020–21 season, Addison was assigned to Minnesota's AHL affiliate, the Iowa Wild. He was recalled due to a shortage of available defencemen for Minnesota and made his NHL debut on February 16, 2021, in the Wild's 4–0 loss to the Los Angeles Kings.[17] He played in three regular season games for Minnesota. With Iowa he appeared in 31 games, scoring six goals and 22 points and was named to the AHL's 2020–21 All-Rookie Team.[18] The Wild made the 2021 Stanley Cup playoffs and faced the Vegas Golden Knights in the first round. Addison made his NHL playoff debut on May 24, replacing the injured Carson Soucy, registering an assist on Jordan Greenway's goal in the first period of the Game 5 victory.[19] The Wild were eliminated by the Golden Knights, and Addison registered just the one point in three games.[7][20]
He began the 2021–22 season with Iowa and appeared in four games before being recalled by Minnesota on October 29.[21] He made his NHL season debut on October 30 in a 4–1 loss to the Colorado Avalanche.[22] In the next game on November 2, 2021, he scored his first NHL goal against goaltenderFilip Gustavsson in a 5–4 overtime win against the Ottawa Senators.[23] He spent the rest of the season bouncing between Iowa and Minnesota.[24][25] He finished the season playing in 15 games with Minnesota, scoring two goals and four points. In 43 games with Iowa, he registered seven goals and 34 points.[7] Addison made the Wild's opening night roster for the 2022–23 season and registered his first three-point game on October 17, 2022, assisting on all three goals by the Wild in a 6–3 loss to the Avalanche.[26][27] He had his second three-point in the season on January 4, 2023, scoring one goal and assisting on goals by Kirill Kaprizov and Joel Eriksson Ek in a 5–1 victory over the Tampa Bay Lightning. He was the first rookie defenceman in franchise history to record multiple three-point games in a season.[28] However, towards the end of the season, he struggled and was a healthy scratch for many games, especially after the Wild acquired defenceman John Klingberg at the trade deadline.[29] He finished the season with three goals and 32 points in 62 games.[7]
A restricted free agent in the offseason, Addison signed a one-year contract with the Wild.[30] He once again made the opening night roster for the Wild in the 2023–24 season but was passed on the team's depth chart by Dakota Mermis and Daemon Hunt. On November 8, 2023, Addison was traded to the San Jose Sharks in exchange for Adam Raška and a 2026 fifth-round pick.[29] He made 12 appearances with the Wild, registering five assists.[7] He made his Sharks debut on November 9 in a 3–2 victory over the Edmonton Oilers.[31] He registered his first point with the Sharks on November 20, assisting on Tomáš Hertl's goal in a 3–1 loss to the Vancouver Canucks and scored his first goal for the team and of the season in a 5–4 loss to the Vegas Golden Knights on December 10.[32][33] He finished the season appearing in 60 games for the Sharks, scoring the one goal and 12 points.[7]
