The Bruins and Marchand had discussions on a contract extension, but could not come to terms before the trade deadline, which led to the Bruins trading their 37-year-old captain.
As Marchand joins the Panthers, some believe there is a possibility of him rejoining the Bruins in the off-season as a free agent. For now, however, he went from a beloved player in Boston to one of their most hated rivals, and now Bruins fans will understand why every other fan base despises him.
