General manager Don Sweeney is getting a head start on keeping Brad Marchand in Boston.

The Bruins winger is an unrestricted free agent once next season ends, but both sides have begun discussions on a potential contract extension, according to multiple reports.

Sweeney made it clear in June he wants to begin negotiations sooner rather than later, calling the 28-year-old a "big part" of the team.

Marchand showed his importance to the Bruins last season, reaching career highs in goals (37) and points (60).

Entering the final season of his contract, Marchand carries a cap hit of $4.5 million, and based on his spike in production, it's justifiable to believe he'll be receiving a raise.
