In 1970, the average NFL player lasted nearly five years in the league. By 1986, he had a three-year stay, a downward trend that continued as the league adopted more pass-happy formations, such as the West Coast offense, according to the NFL Players Association. A vested NFL player (meaning they get their pension after retirement) has to play a least 4 years. It's a short stay for most and this is why you see athletes trying to get the most money from NFL owners. Most NFL players as of 2010 play for an average of 10 years, but it also depends on the position that you play and the shape that you are in.
