His YPC by game, in order: 7.2, 6.1, 4.5, 2.2, 4.5, 6.5, 3.8, 3.9, 7.4, 3.4, 3.4. He's doing this with one of the top few pass offenses in the league for a team that has been in the lead for almost all of the time in almost every game. He's good, but he's not "win games by himeslf- Barry Sanders" good, at least not the large majority of the time. Maybe not this year, but that is because the Vikes are throwing the ball a lot more. But I am confident that Peterson could take over any game whenever he wants to.
