The point of your post is...what? That part is explicitly covered in the rules in that you can't punch/forearms/yada yada to the head. The point we're discussing is not explicitly covered, it's an interpretation of more general rules, which is why there is debate.
The point is why do you care about what happened to an OSU player, on a completely legal football play when OUR quarterback got uppercutted and his head slammed into the turf?
It wasn't a legal play, it was an illegal hit. And hit on Taylor was flagged, wasn't it?
The difference is the hit on Taylor was illegal, and the hit on the OSU kid wasn't according to... ya know... THE RULES. Which you are still ignoring.
