In most U.S. states sports such as baseball and football rule supreme but in Michigan many young boys grow up with hockey as the number one sport of choice. That was certainly the case for Gary Morrison, who had a natural talent for the game from an early age. After high school he enrolled at the University of Michigan, perennially a powerhouse team in the NCAA. As it happens Morrison was a member of the school when it was at the very pinnacle of its success. The Golden Gophers won the NCAA title in his freshman and sophomore years in 1974 and 1976. Despite being a forward, Morrison was never known for his point-scoring abilities. He was a defensive specialist whose main objective was to shut down the opposition's top stars. In fact he scored just 42 points during his four years in the NCAA.
Upon turning pro in 1977-78, Morrison inked a free-agent contract with the IHL's Milwaukee Admirals. In 78 games he notched 21 goals and 42 points. His surprising newfound offensive touch came as a surprise not only to Morrison but also the Philadelphia Flyers, who signed him to a minor-league deal. He joined the Maine Mariners of the AHL and continued to show signs of becoming a solid all-round player.
Morrison's strong work ethic was beginning to pay huge dividends and in 1979-80 he had the best year of his pro career, scoring 29 goals and 52 points in 75 games with Maine. The excellent improvement in his game also garnered him a three-game stint with the Flyers, where he tallied a pair of assists.
In 1980-81 Morrison played in 33 games with the Flyers where he had a goal and 14 points. He played a handful of games with Philadelphia the following year but spent most of the season back in Maine. He retired after the 1981-82 campaign at the age of 26.
