With Otto Graham as your offensive coordinator and the ability to hit a wide receiver on a dime, you're bound to be a pretty good pro. Sonny Jurgensen may be the second best pure passer on this list and another clear-cut gunslinger.

A five-time All-Pro and Pro-Bowler (1961, 1964, 1966, 1967, 1969), Jurgensen set a plethora of records during his playing career including most single-season touchdown passes (32) and most passing yards (3,723) in 1961. In 1967, Jurgensen broke his own passing yards record with 3,747 yards, as well as NFL single-season records for attempts (508) and completions (288).

Although he only played in one game during the postseason in his career (at the age of 40 in his final season) Jurgensen played bigger than he was and more athletically then he seemed. At 5'11'' with a pot belly, he didn't look much like a pro athlete but come Sunday afternoon he was one of the best.

What made him a gunslinger other than his arm was the nightlife he partook in, his fearlessness and his nasty demeanor on the football field. He played without fear despite being small and looking like Homer Simpson. Kudos to you Sonny.
