When really mad at a person, I guess the instinct in some is to immediately punch that person in the face.
For Antrell Rolle, that's even true when that face punch could get him thrown out of a game, will certainly be penalized, and, because the other guy is wearing a helmet, will do him no harm whatsoever. There is no potential positive outcome for Rolle here. Zero upside.
But hey, the fist wants what the fist wants.
That's probably as much of a punch as a guy can throw without getting ejected. It came late in the game, with things all but decided after Chris Johnson had worked over the Giants. Rolle just got frustrated and lost his mind for a minute.
