Easy Brett Favre
Because football is a team sport, it's hard to say who is the best all time player because a great player still needs a strong supporting cast around him; also, a very good player can be made to seem better because he has an exceptionally strong team around him. For example, a quarterback with extremely high ratings has receivers who can catch the ball, or his stats would not be so high; and a very good quarterback who has very poor receivers around him will be perceived to be weak. Just as a good running back needs good blockers, a great running back without blocking will not get very far.
Still, some unquestionably great players you will find mentioned in any conversation will include Jim Brown, Joe Montana, Deacon Jones, Brett Favre, Jerry Rice, Lawrence Taylor, Emmitt Smith, Johnny Unitas, Dick Butkus, Joe Greene, Steve Young, Walter Payton, Dick "Night Train" Lane, Marshall Faulk, Mike Singletary, and a host of other great players.
