The National Football League was formed in the 1920's, some nine decades ago. Over that period, there have been many stars on both sides of the football.
I will rank my top 50 greatest NFL defensive players, in the history of the league. What were the factors I used to pick these great players?
First, any defensive player in the Hall of Fame is a strong candidate. Pro Bowl and All-Pro selections are also great indicators of how well a man played in his era, against his peers.
Outstanding players who are currently active or have just recently retired and are not yet eligible for the Hall of Fame are also highly considered.
The other criteria I used was longevity and the dominance that player displayed during his career. Obviously, there is a difference in style of play and athleticism over the decades, but what I was really looking for was the dominance of that player during his tenure in the league.
