Why do some nfl players have a c on their jersey?
The C indicates a team captain.
The 'C' on a player's uniform denotes that the player is one of the captains of the team. It also depends on what year the jersey is from. Champion used to make NFL jerseys - the C is their logo. The NFL has since switched to Reebok - maybe a season or two ago? The "C" stands for "captain," and each captain is elected for a one-year term to be a captain. Not all captains…
The "C" is like the captain in hockey. There will be anywhere from one to four captains on a team. A team is allowed five captains with only four speaking, hence the four stars on a jersey. If a player has one star in yellow, he is one of four captains. Peyton Manning has three stars because he is the speaking captain with the other captain being on defense.
