Peterson is now 30 and has carried the ball 2,054 times in his career. He should be fresh though after sitting out all but one game last year due to suspension. Peterson is a genetic freak, so traditional benchmarks we use to downgrade running backs like age and carries don't really apply to him. He's in exceptional shape and plenty motivated to make up for his lost season. Peterson has eclipsed 1,200 yards in six of his eight seasons and scored double-digit touchdowns every year until 2014. He's still every bit a fantasy stud.
