The thing is though a 4th liner probably wouldn't stay down.. the NHL is starting to condition players to react like soccer players (they didn't always flop like they do now) because it gets results, heck the discipline committee admitted the injury played a factor in the suspension - that's an awful slippery slope to start down.
Debate aside of if Hansen had the ability to hulk him out with an immense force from his fore-arm or if Hossa just is adverse to contact, watching the replay you can see after contact he drops himself (watch the legs) so I'm inclined to think he was playing it up and then the trainers/"concussion room" parties get involved and it's taken out of his hands. I think this is backed up by the fact he isn't expected to miss anytime but was apparently hit hard enough to warrant two minutes on the ice. Not to say he wasn't wronged - as any shot to the head should be punished, but by altering calls based on how much damage an act did to a particular person and not the act is just wrong.
If that crap happened to Zenon Konopka you can be sure he'd snap back up and be on the warpath.
Man our feud with Chicago has to be one of the best in pro sports and it just keeps getting more baggage added, got to love it.
This is why I don't mind Kesler diving and embellishing all over the ice. I love it when he makes fool of those refs who can't even get an offside rule right. There is no integrity in this game so I don't mind having players like Kesler on our team to even the playing field. I'd say if you can't beat them, join em.
