I'm not even sure how you diffuse a situation like this. The calling official went INT right away (probably was thinking flagrant) and closed down to the player on the ground. It would take some darn quick thinking by the other refs to keep the benches from exploding, but the coaches have to do a better job of that. In this case it would probably be easier to note the players left on the bench and eject everyone else. That is, if the game is going to be finished which clearly here was not the right option.
