San Francisco 49ers (1946 - 1967)

Before Steve Walsh, Joe Montana, Ronnie Lott, band co. made San Francisco one of the finest franchises in NFL history, the 49ers rocked an actual Forty-Niner shooting a gun on their helmets. Maybe the recent parking lot shootings and stadium brawls are a result of more than just fans feeling rejected by their mommies. It seems like the attitude is in the team's tradition.
