Blaine Stoughton played his junior hockey with the Flin Flon Bombers and led the team for four seasons while leading the league in goals for the 1971-72 season. He was also named to the all-star team. When the pros came calling in 1973, Pittsburgh in the NHL and Quebec of the WHA drafted Stoughton. He chose to stay with his team and finish the season where he began.
He made his NHL debut in the 1973-74 season with the Penguins but played more games with the team's AHL affiliate in Hershey. In the off-season, Stoughton was traded to the Maple Leafs where he played his first full season in the NHL in 1974-75. Stoughton also saw his first action in the Stanley Cup playoffs this year but split the next year with the Leafs and their CHL team in Oklahoma City.
The 1975-76 season saw Stoughton's rights to play in the WHA come up once again when he chose to play for Cincinnati, wa team which had received his rights from Quebec in the league's Expansion Draft. Stoughton finally saw regular ice time and played in the league for three seasons until he was claimed by Hartford from Toronto when the NHL expanded in 1979. In his first year back in the NHL, Stoughton led the league in goals and topped off his point total with 100.
Stoughton was a Whalers for five seasons and represented the team at the 1982 All-Star Game. He was traded to the Rangers in 1984, his last year in the NHL. Stoughton played the 1984-85 season in the AHL, took the next year off and then traveled to Italy to play one last year of hockey, retiring in 1988.
