In the NFL, players who have been chosen as team captains frequently sport a "C" badge on their jerseys. The "C" patch is a standard design used by all teams participating in the captaincy program. The patch is in team colors and is worn on the front left or right breast, depending on other patches worn by the specific team. The number of gold stars on the patch represents the number of years that player has been named captain by a team. If a player has been named captain for longer than four years, the "C" on the patch is gold. The NFL implemented a program in 2007 that allowed teams to designate up to six players to wear a "C" on their jerseys. However, teams are not required to designate captains, and some teams choose captains on a weekly basis, avoiding the "C" patch altogether.
