Here is the video of the huge hit Marc Staal laid on Matt Stajan. The hit is being seen in completely opposite fashions based on which team a person supports, but in trying to be as unbiased as possible I see a clean hit where Staal takes him on the opposite shoulder and not the head, stays on the ice the entire time and there is no doubt he rocked him. I do not see it as being from the blindside as some are saying. You be the judge and leave it in the comments.
Update: Link to my analysis of the hit which has other video of the hit
