After a season with his hometown Toronto Marlboros, in which he produced more than a point a game both in the regular season and in the playoffs en route to a Memorial Cup championship, Tom Edur, born November 18, 1954, signed as an underage free agent with the World Hockey Association's Cleveland Crusaders. After his first season with the Crusaders, where the defenseman scored seven goals and 38 points, he was draft eligible in the National Hockey League, and the Boston Bruins selected him 54th overall.
Edur spent two more seasons with Cleveland, though he never topped the point total he posted as a rookie. The Boston Bruins traded his rights to the Colorado Rockies in September of 1976 and he made his NHL debut shortly after.
Suiting up for all 80 games as a rookie, Edur scored seven goals and added 25 assists for the Rockies. The 32 points were good for tops among Rockies defenseman. Coupled with a solid +14 rating, Edur had a very impressive debut season in the NHL.
In his second year, Edur had 12 points through the first 20 games with the Rockies but was shipped to the Pittsburgh Penguins in exchange for defenseman Dennis Owchar. With the Penguins, Edur excelled offensively scoring 43 points in 58 games. However, his defensive game suffered with the Penguins and he was a minus-nine despite his scoring ability.
In the end, it was his last season of professional hockey for Ontario native Tom Edur. Despite racking up 55-points between Colorado and Pittsburgh, and again leading his team in scoring from the blue line, Edur didn't play again after the 1977-78 campaign.
