The league really needs to throw the book at this guy and he should probably be suspended through part of the playoffs as well for what he did last night, not to mention his long history of dirty crap and the fact that he's been suspended before.
Whether it's last night, the face slash on Jeff Carter 2 years ago, the elbow on Daniel Sedin in 2012, the hit on T.J. Oshie, the elbow on Ruslan Salei, the head shot on Matt Cooke in 09, etc. it's time for the NHL to teach this douche a lesson and send a message. Sounds like he has an in person hearing, so we'll see what the league decides. It should be lengthy though.
