Once again the targeting rule goes too far. Pittsburgh QB lowers his head at the last second while outside the pocket and his helmet connects with the helmet of a Notre Dame defender. They throw the penalty and didn't reverse it.
Wouldn't you interpret the word "targeting" as purposely going at someone's head? If the QB continues to run as he was, that would have been a perfect tackles with the head/shoulder into the guy's gut. Seriously, if this is considered targeting, then it can easily be called a half dozen times a game, if not more.
