Left winger Mike Dwyer was born in Brampton, Ontario on September 16, 1957. Following his second season of junior hockey, Dwyer was drafted by the Colorado Rockies 74th overall in the NHL Amateur Draft. After a season of apprenticing in the minors, Dwyer made his NHL debut with the Rockies in 1978-79.
Dwyer played 22 games over two season with Colorado, spending the majority of his time with minor-pro teams in Philadelphia, Forth Worth, and Birmingham. A strong run with the Birmingham Bulls during the 1979-80 season caught the attention of the Calgary Flames who signed Dwyer as a free agent prior to the start of the 1980-81 season.
The change of scenery didn't change Dwyer's luck at the NHL level, however, as he managed to play just nine games with the Flames over the next two seasons. His last season of pro hockey, 1982-83, was spent entirely at the minor pro level with the Colorado Flames.
Dwyer retired with 31 NHL games under his belt and two goals and six assists to his credit.
