I BELIEVE GEORGE BLANDA OF THE Oakland Raiders HAD THE LONGEST NFL CARREER (WELL OVER 20 YRS.). Blanda played in the AFL (not the NFL) from 1960-1969. So you can take 10 years off of his total if you take the question literally. Correct answer for longest NFL career would be Morten Andersen. With 25 seasons and the NFL record for most games played at 382. Blanda is third on the list behind Andersen and Gary Anderson.
Arnold Palmer, professional golfer. The previous answer was extremely misleading as hundreds of players have gone well past 20 years.
morten Anderson nfl from 86 to 08
wel a career cluster an nfl player could have is mabey the player is traded to a differeant team and does not get paid enough money.
Including all player positions, the average NFL career is four seasons.
BenJarvus Green-Ellis has the longest streak of carries to start an NFL career without a fumble (589).
Probably Brett Favre who is in his 19th or 20th year in the nfl and who now plays for the minnestota vikings
