It’s literally been years since the Steelers let a running back rush for over 100 yards against them, but this week they’ll face a tough challenge when they go up against Adrian Peterson and the undefeated Minnesota Vikings. Peterson rushes for over 100 yards in over 80% of his games and often goes for 150 or more. The Steelers still have a stalwart run defense, but their secondary is becoming a little suspect. If the Vikings can spread out the Steelers with the passing game they might be able to soften up the middle of the field enough for Peterson to break the Steelers incredible stingy run defense streak.
