Peterson gets the nod over the likes of Emmitt Smith, Eric Dickerson, Gale Sayers, LaDainian Tomlinson and O.J. Simpson because he has already piled up impressive numbers while showing no signs of slowing down as he approaches his thirties. He topped 10,000 career yards last week and he has scored 86 rushing touchdowns. And last season, Peterson had one of the best seasons ever, rushing for 2,097 yards and coming up just shy of Dickerson's single-season mark -- less than a year removed from a major knee injury.
