As a rookie in the 1981–82 season he scored an impressive 26 goals and totaled 67 points, which would prove to be the second highest point total of his career, behind his 73 in the 1989–90 season as a Toronto Maple Leaf.
During the 1983 off-season he was traded to the New York Rangers in the trade that saw popular Ron Duguay leave the Big Apple.
