Steelers linebacker James Harrison understands his hit on Browns QB Colt McCoy was illegal by the letter of the law. He can also understand, grudgingly, why the NFL suspended him one game as punishment for a series of similar hits over the last three seasons. What Harrison doesn’t quite understand, however, is why the Browns haven’t also been disciplined by the league for allowing McCoy to return to the game so quickly if the QB was in such bad shape.
