James Harrison of the Pittsburgh Steelers is known as one of the best defensive players in the NFL. He has also earned the reputation of being mean, hard nosed, and at times dirty. Harrison claims he's not dirty, but that NFL commissioner Roger Goodell branded him as such. He also ripped his quarterback Ben Roethlisberger for some costly mistakes he made in the last Super Bowl, as well as calling Steeler running back Rashard Mendenhall a "fumble machine."
