Aside from getting blown out again, Oakland is facing a brutal situation with running back Darren McFadden, who was unable to play Sunday because of a sprained ankle. McFadden is expected to be back next week, but is not having anything close to the performance he had in 2010, when he averaged 5.3 yards per carry. He is set to be a free agent after the 2013 season. McFadden is averaging only 3.3 yards this season because the Raiders have primarily played a zone-blocking system that simply doesn't work for him. Two weeks ago, McFadden, at the urging of owner Mark Davis, talked to the coaches about the situation, according to a source familiar with the circumstances. The coaches went back to a more favorable system and McFadden responded with 114 yards against Kansas City before getting hurt the next game against Tampa Bay. If the Raiders are going to maximize McFadden's ability, they need to change the offense. If not, they would be better off trading him in the offseason.
