You don't have to bomb on him or whatever - if you want to get at him that badly, just do like enforcers used to and just start throwing so he doesn't have a choice and don't stop until the linesmen or his teammates pull you off. A supposed character tough guy like Prust spearing some five foot rat in the groin is embarrassing.
Eh, if Marchand was the type of player who would man up and fight back then I'd agree. But he'd just turtle and then spear/board/high stick you the next time you play each other.
Like I say, ****** move but to a player who has made a career of ****** moves. Seems hypocritical to grant him respect when he has rarely ever shown it himself.
