The native of Strathroy, Ontario, has played in 225 career National Hockey League regular-season games, all with Montreal, and has accumulated seven goals and 53 assists for 60 points. After finishing his final season with the St. John's Sea Dogs, Beaulieu split time between Montreal and their AHL affiliate, the Hamilton Bulldogs. The nail in the coffin was Beaulieu being a healthy scratch during Game 6 of the first round of the postseason against the New York Rangers.
Beaulieu was projected as a mobile, puck-moving defenseman with size, offense and the ability to qb the powerplay.
Last season, the defenceman struggled. "After just a handful of games, [then head coach] Michel Therrien decided he had seen enough".
"Obviously, it's disappointing", Beaulieu said of being a healthy scratch against NY, per the Montreal Gazette. In 17 career playoff games, Beaulieu posted four assists.
The deal was struck just before National Hockey League teams were required to submit their protected lists for the Vegas Golden Knights expansion draft.
Beaulieu immediately improves the Sabres' blue line under new coach Phil Housley, a Hall of Fame defenseman.
