Morrison was originally a fourth-round pick of the Rangers in 2015 before turning pro in 2019 and signing with the Kings. In his first professional season, he had 20 points (10G / 10A) in 50 AHL games but spent all of 2020 in the ECHL, where he had six goals and 13 assists (19 points) in 17 games. This is more of a salary dump for Chicago--Maatta had two years left at $4.083M AAV but the Blackhawks will retain $750K per year.
