Brad Marchand is a pest in all senses of the definition. He's annoying to play against, with relentless tenacity and a neverending motor, and his personality is abrasive.
Going back a few days ago, there was a wild scrum between the LA Kings and Anaheim Ducks, where goaltender Pheonix Copley threw a commanding punch to the face of his opponent.
Copley was given a game misconduct, but no suspension. This clearly angered Marchand, who has seen himself watching from the press box several times in his career.
