Fouts? Humphries? Where does your favorite of all time stack up?
The Chargers have seen their slew of great quarterbacks since their establishment in 1959. The AFL was infamous for high-powered offenses, but since the AFL-NFL merger, the Chargers have had some great quarterbacks leading their offensive attack as well.
Honorable mention: Johnny Unitas
Though unquestionably one of the greatest, since Unitas only played with the Chargers for one season, I don't think he can be considered one of the Chargers' greatest quarterbacks.
