4. Steelers DL Ernie Stautner
Age: 38 years, 7.8 months
This one goes way back. Ernie Stautner was a talented defensive lineman whose career began all the way back in 1950. Despite playing in a completely different era of football, Stautner was able to outlast most everyone he played with at the time en route to an illustrious football career.
Stautner didn’t earn his first Pro Bowl until the age of 27 in 1952. From there, however, he was selected to the Pro Bowl in 9 out of his 10 seasons in a row — earning All-Pro honors at his peak in 1958. Stautner would play two more years and he started just 2 games in his final season over 38 years and 7 months old.
As one of the greatest Pittsburgh defenders of the era, Stautner was elected to the Pro Football Hall of Fame as a member of the class of 1969. He was also an inaugural member of the Steelers Hall of Honor as a member of the Class of 2017.
Stautner passed away on February 16th, 2006 at the age of 80. He was one of the first in a line of many great defensive linemen that would come to Pittsburgh, and he played all 14 professional seasons as a member of the Steelers.
