Experimentation with the uniform design began in 2002. An alternate orange jersey was introduced that season as the NFL encouraged teams to adopt a third jersey, and a major design change was made when solid brown socks appeared for the first time since 1984 and were used with white, brown and orange jerseys. Other than 1984, striped socks (matching the jersey stripes) had been a signature design element in the team's traditional uniform. The white striped socks appeared occasionally with the white jerseys in 2003–2005 and 2007.
