Addison was a second-round pick (No.53 overall) in 2018 and has had a terrific season with the Lethbridge Hurricanes (WHL). The 19-year-old has scored 10 goals with 33 assists (43 points) in 39 WHL games and will likely report to Iowa (AHL) once his season is over.
Galchenyuk’s career has completely crumbled into pieces. After posting 50-plus points in two of his last three seasons with Montreal, Galchenyuk has been traded three times in two seasons and has just 58 points (24G / 34A) in his last 117 games, including 17 points (5G / 12A) in 45 games this year. He will likely fill a similar bottom-6 role in Minnesota. Galchenyuk will be an unrestricted free agent at the end of 2020.
Zucker has scored 14 goals with 15 assists (29 points) in 45 games with the Wild this season. Zucker, who is a one-time 30-goal scorer, will get a huge fantasy boost because he will likely slot in the top-6 with Sidney Crosby or Evgeni Malkin. After this year, Zucker has three years left with a $5.5M cap-hit (per PuckPedia).
Frolik is in the final year of his five-year contract that carries a $4.3M AAV cap-hit and gets acquired for the same fourth-round pick that the Sabres acquired from Montreal for Marco Scandella. Frolik has scored five goals with five assists (10 points) in 38 games this season but has played a much smaller role than in previous seasons. With Jeff Skinner out, the Sabres were looking for some wing help in their middle-6.
Scandella suited up in 31 of 41 games this season, scoring three goals with six assists (nine points) while averaging 1.23 hits and 1.1 blocked shots per game. Scandella is in the final year of his five-year deal that carries a $4.0M AAV cap-hit. He joins the left-side of the Canadiens' blueline that includes Ben Chiarot, Brett Kulak and Victor Mete.
