Mellanby, a hard-working forward, made two trips to the Stanley Cup Final and scored 364 goals during 21 NHL seasons with five teams.
The Philadelphia Flyers selected the Montreal native in the second round (No. 27) of the 1984 NHL Draft and signed him after he played two seasons at the University of Wisconsin. Mellanby made his NHL debut March 22, 1986, and he became a regular the following season. He had 32 points (11 goals, 21 assists) in 71 games in 1986-87 and helped the Flyers advance to Game 7 of the Stanley Cup Final before losing to the Edmonton Oilers.
