Mario Roberge took a long and winding path to the NHL that started with the Quebec Ramparts of the QMJHL in 1981. After three seasons of moderate success, he was passed over in the NHL Entry Draft. As such, he booked his own ticket to the top, putting in time in Riverie-Du-Loup, St. John's, Virginia, and Port-Aux-Basques before he was finally able to sign as a free agent with the Montreal Canadiens in 1988.
The Habs promptly placed him with the Fredericton Canadiens of the AHL where his aggressive style and willingness to fight were in full display. He led the league in penalty minutes during the 1990-91 campaign. For his feistiness Roberge was rewarded with a trip to Montreal just ahead of the playoffs where, for the most part, he road the bench as pugilistic insurance.
The following season, Roberge saw only limited action due to injuries. But in 1992-93, he got his best run in the NHL, appearing in 53 games. From there, his stock with the Canadiens fell into decline. In his ninth game of the 1994-95 campaign, he broke his ankle while fighting Kris King. By the time he healed, the numbers game dictated his departure to Fredricton of the AHL.
Roberge completed his career in the minors, playing for Mohawk Valley and St. Georges-de-Beauce where he retired in 2001.
