He intentionally made contact with the crown of his head. It's absolutely a T.
Change the rules of the game for different times of the game? I never agree with that. He intentionally contacted a ref to intimidate. What's next? A light headbutt is ok as long as it's a one possession game and within ten seconds remaining? If so, put it in the rules. And the refs would not have changed the outcome of the game. D*ckhead Danny would have changed the outcome. The refs would enforce the behavior which is what they are paid to do.
