Umm.. Andy, they made a new rule because of it. The guy was 20 yards AWAY from the play and Sapp blind-sided him. And it wasn't Chad Clifton's jaw. It was his hip and pelvis where ligaments were torn. (yes, I am correcting myself also).

You clearly are not thinking about the same play. Cribbs did not "duck his head" as contact was being made. Cribbs was already in the grasp of Woodley when Harrison hit Cribbs in the head. Cribbs was already forward before Harrison put his head down and hit Cribbs on the back side of Cribbs' Helmet. Sorry, but THAT is a BS hit and it's 100% disingenuous of you to claim otherwise. And if you need the actual PROOF, just look at the 40 second mark of this video..

Clear as day that Cribbs head is down and Harrison's is NOT. Harrison is the one who put his head down and initiated the helmet to helmet contact. Headhunting. Plain and simple.
