2. Bill Romanowski – 49ers, Eagles, Broncos & Raiders:
Romanowski was a powerful force who played linebacker with the utmost ferocity. But he took that a bit too far more often than not. He was known for repeated cheap shots and late hits.
Perhaps his most notorious dirtiness, however, came when he was repeatedly accused of being racist. The incidents that prompted the accusations were when he kicked RB Larry Centers in the head and spat on San Francisco receiver J.J. Stokes. He topped all that off by physically removing Eddie George’s helmet in 2002. He even punched former teammate Marcus Williams during a scrimmage scuffle in 2003, forcing him to retire when he broke his orbital bone.
