Unless Peterson suddenly has gotten far better than he has been the rest of this season, I'd say that the big running plays will come from Chester Taylor. AP's average yardage shows that despite his thinking that he runs better without a FB, he has always had better yardage when he had a lead blocker. I love the guy, but he's got to get better blocking and Tony Richardson is on some other playoff team this year.
I think that Percy Harvin is the key to how the Vikes do this week. Also, I think that resting Pat Williams in the last game will have a huge impact when he gets in there this week.
I think it'll be close, and though I want the Vikes to win, I can't say which way it'll go.
