It's been well documented that Vikings Adrian Peterson was agitated that he fell 9 yards short of breaking Eric Dickerson's single-season rushing record a year ago. And in order to raise the bar for 2013, Peterson has announced a personal goal to chase a 2,500-yard season.
But that's not the only milestone the always motivated running back keeps in the back of his mind. Peterson also wants to some day leave the game as the NFL's all-time leading rusher, a record currently held by Emmitt Smith.
Peterson, with 8,849 yards, is approaching the halfway mark to Smith's 18,355-yard record.
