Richard Sherman, Cornerback, Seattle Seahawks
Richard Sherman might very well be one of the most notorious trash talkers on the field. You’ll see him mouthing off to opposing wide receivers all game long. You’ll see him make fake yawning gestures at opposing quarterbacks, making it seem like he’s sleepy from boredom, since quarterbacks will so often avoid throwing the ball in his direction. And, of course, who can forget the infamous interview in January of 2014, when he went on a tirade against former San Francisco 49ers wide receiver Michael Crabtree.
