The easiest rating is 1 which gives the player the advantage against the defense and indicates an easy opponent, the most difficult rating is 10 which gives the defense the advantage and indicates a tough opponent.
The Packers made it a point of slowing him down last week. The Falcons will not be able to do the same on the edges, expect Peterson to return to his usual spot as one of the top fantasy running backs.
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.
