Defenceman Greg Theberge played parts of five seasons with the Washington Capitals. He was a fine passer with good mobility who helped the club's transition game and power play improve in the early '80s.
Born in Peterborough, Ontario, Theberge played junior with the hometown Petes. After recording 80 points in 1978-79, he was placed on the OHA's first all-star team. He was taken 109th overall by the Washington Capitals in the Entry Draft that spring. The young blueliner spent the majority of his first two pro seasons with the AHL's Hershey Bears. He was selected to the league's second all-star team in 1981 after accumulating 65 points for the Bears.
Beginning in 1981-82, Theberge played two full seasons on the Caps' blueline. He recorded 60 assists over this time and registered nine power-play goals. Theberge was also a part of the franchise's first legitimate quality team. After spending more time in the minors than the NHL in 1983-84, the veteran rearguard retired.
