I have noticed that the captains and co-captains on some of the NFL teams wear a "C" on their uniform. Does anyone know what's written under the "C"? I thought maybe Captain, (duh), but it looks like something else and I can't quite make out what it is. Also, how come not all teams are wearing them? They all are in the same script, so I would imagine it is a league mandate, but apparently not. In other sports where they wear them, they usually select their own script. Anyone know?
