With 6 games left Marshawn is trailing AP by 123 yards. Foster is 133 yards back of Marshawn. The Vikings have 5 of their last 6 games against top 10 defenses. The Hawks have 4 games against top 10 defenses but also one game against the worst defense. The Titans* have no games against a top 10 defense but they do have 4 against top 16 defenses. I think it comes down to Lynch and Foster. Unfortunately Foster may be in the catbird seat.
* Edit: I meant Texans not Titans.
