The Moore hit was within the rules....it was delivered with his shoulder, not his elbow. The fact that Naslund was concussed on the hit does not make it a dirty hit...when you get drilled with a shoulder to the head when you are looking down at the puck, you almost always get knocked silly. Bertuzzi's assault from behind on Moore is a whole different scenario: a premeditated sucker-punch and then a bulldog from behind that was a deliberate attempt to injure.
