In Sunday's Eagles-Browns game, Browns rookie running back Trent Richardson absolutely demolished Eagles safety Kurt Coleman. Richardson lowered his head and smashed it directly into Coleman's head, sending the defensive back's helmet flying as Richardson picked up nine yards on the play. He'd be stopped behind the line on the next play, and the Browns would be forced to punt to end the drive.
