When he stepped on the ice for his first NHL game in 1982, Campbell officially became the biggest hockey player in the league. When he was four and five, he ran across the street to the local rink and asked the caretaker to let him play, which he did, for hours on end. That was where his NHL dream began, but once realized it didn't endure.
Undrafted while playing university hockey in Alberta, he caught on with the Jets in 1982, but despite his physical play, he became a spare part the following year and spent more time in the minors than with the Jets, though he did play all of 1983-84 with the team.
Campbell was traded to Boston for Bill Derlago on January 31, 1986, but again in Boston he saw more action in the minors than with the Bruins. In 1988, he decided to play in France for two years, and after two more years in the AHL he retired.
