We could spend all night hashing through Peterson statistics, but there are two that I think best illustrate his season. He led the NFL with 27 runs of at least 20 yards, more than twice that of the next-highest player. At the same time, he led the league with 1,019 yards after contact, according to ESPN Stats & Information.
Among other things, that means Peterson was by far the most explosive and the most powerful running back in the league this season. Those attributes are often mutually exclusive, but Peterson combined them both in a season that will go down in the ages.
