Cockiest Quote: "We're going to win Sunday. I guarantee it."

Joe Namath was the "quarterback sex icon" long before Matt Leinart ruined the franchise. His full head of hair, charming personality, and athletic ability taught kids of the '70s what it meant to be a man. Some of us don't have the courage to hit on a girl when we're drunk at a frat party, but Namath did it on live tv, at 60 years old no less. He's a total boss. His cockiest moment came in Super Bowl III when he guaranteed victory against the Baltimore Colts who were billed as "the greatest team of all-time." You know Broadway Joe backed it up with an improbable win.
