"Habs elected for one-year award for Subban because they can take him to arb next summer," Campbell tweeted on Wednesday. "Also can negotiate new deal earlier on one year."
Subban was selected by the Canadiens with the 43rd pick in the 2007 draft. He has played 284 games with the club, recording 42 goals, 125 assists, and a plus-10 rating. He won the Norris Trophy as the league's top defender in 2013.
