Johnny Unitas, Super Bowl V - 37 years, 8 months
John Constantine Unitas (1933–2002) spent 18 seasons in the NFL, mostly with the Baltimore Colts. He was consistently ranked as one of the finest NFL players of all time during a career that lasted from 1956 to 1973.
Unitas was awarded Most Valuable Player three times in 1959, 1964, and 1967, as well as receiving ten Pro Bowl and five first-team All-Pro awards. He was a part of the Colts winning four championships: three in the pre-merger period (1958, 1959, 1968), and one in the Super Bowl era (Super Bowl V).
His first championship triumph is recognized as one of the finest in NFL history, and it is credited with popularizing the league. He set the record for most consecutive games with a touchdown throw with 47 between 1956 and 1960, which he held for 52 years.
Unitas, sometimes known as "Johnny U" and "Golden Arm," was the prototypical headline quarterback of the contemporary era. In 1979, he was elected to the Pro Football Hall of Fame.
