that was one hell of a hit. he was in so fast the handoff had not been compleated. WOW
As a michigan fan watching this game all I could do was

But what about the hit and the aftermath of it in the game?
Was it helmet to helmet? What about excessive celebration? I thought a flag could have been thrown, but still WOW

The helmet can be used as a spear to inflict punishment on the opponent. running backs do it all the time, and blockers and tacklers do as well. Rules changes have tried to address the issue of concussions, including helmets being used as the lead device to hit an opponent in his head (helmet to helmet flag).
I offer a view of a more form tackle
http://www.youtube.com/watch?v=RHIAHaDWZuk The defender leads with his shoulders and the side of his helmet and delivers a punishing blow. The recipient of the hit was injured, but not in the head. This is how tackling should be taught and practiced by its players.
It is up to the officials to set a standard and enforce the rules. We can maintain the game for what it is, clean it up a little, and maybe we will have less devastating instances as a result. Nevertheless, the game is rough, and when a 6'6" 235lbs physical masterpiece gets a chance to show off, watch out
