Mike Nykoluk's journey in the world of hockey began in the minor leagues, where he honed his skills and developed a deep understanding of the game. Born in Toronto, Ontario, Nykoluk played junior hockey with the Toronto Marlboros before moving on to the professional ranks. His professional playing career was primarily spent in the American Hockey League (AHL) with the Hershey Bears, where he became a central figure on the team.

During his time with the Hershey Bears, Nykoluk was known for his playmaking abilities and leadership on the ice. He played as a center and was recognized for his ability to read the game and set up scoring opportunities for his teammates. Over the course of his career with the Bears, he accumulated impressive statistics, becoming one of the team's all-time leading scorers. His performance in the AHL earned him the Les Cunningham Award as the league's most valuable player in 1967.

After retiring as a player, Nykoluk transitioned into coaching, where he continued to influence the game. He began his coaching career as an assistant coach with the Philadelphia Flyers in the National Hockey League (NHL).

Nykoluk's role as an assistant coach was instrumental in developing strategies and working closely with players to enhance their performance.

In 1981, Nykoluk took on the role of head coach for the Toronto Maple Leafs. His appointment marked a significant moment, as he became the first individual to move directly from an assistant coaching position to a head coaching role in the NHL. Nykoluk's time with the Maple Leafs was challenging, as the team was in a period of rebuilding. Despite the difficulties, he worked diligently to develop young talent and instill a competitive spirit within the team.

Nykoluk's coaching career with the Maple Leafs lasted until 1984, after which he stepped away from coaching in the NHL. Throughout his career, both as a player and a coach, Nykoluk was respected for his knowledge of the game and his ability to connect with players.
