First off, I do not in any way condone what TJ did after scoring the TD. That being said, have you ever seen the throat slash move done with both hands going in the opposite direction? When I saw the replay, I thought he did the money sign, then the superman move where you "rip open the shirt". I guess if his thumbs weren't out it would have been acceptable? I thought the throat slash move was done with one hand at the throat.
