The problem that I have with the hit is that he went for the head. Was it intentional? Maybe, maybe not but the guy was in a very vulnerable position and he took a run at his head.
The second replay is telling. It basically show's the ref's point of view. It looks really nasty - like a vicious elbow to the side of the head. So it's easy to see why he would make the call. From the other replays, yes it looks like a "clean" hit by NHL rules.
But weather a hit is clean or legal isn't the only thing we should be looking at. As players get bigger and stronger the potential for serious injury increases. Should a player be allowed to blind-side an opponent and clobber him in the side of the head with his shoulder (all but assuring a concussion, or worse)? I have a real problem with that.
I'm not saying that this was the Swedish player's intention, but when you intentionally go looking to maim someone, even if it's "within the rules" you should be penalized.
