watch it again, Suh takes cutlers helmet off with both hands. Interested to see if TT watches this and still says it was clean. Rule 12, Section 2, Article 8 Impermissable Use of Helmet and Facemask (j) any player who grabs a helmet opening of an opponent and forcibly twists, turns, or pulls his head. I'm assuming that the opening in which your neck sticks out of the bottom of the helmet counts. I think thats a safe assumption, though.
