Each new detail of this story sounds like the next in the buildup to the punchline of a joke. Adam Jones aka "Pacman" didn't like getting blocked down the field by rookie wide receiver Amari Cooper and Cooper getting a bit rough with him so Pacman takes Cooper down, sits on his chest, rips Cooper's helmet off, grabs Cooper's head and smashes it against his own helmet.
Whoa, that's an ejectable act.
No, three refs were right there and threw the flag the moment they saw it.
Actually, no, they weren't because then the refs threw the flag for another Raiders player defending his teammate so the penalties offset.
