Willis McGahee claims he's going to play but that has yet to be seen. We'll know more today. If he doesn't he still is going to split time with Knowshon Moreno. That being said, last week he had 63 yards splitting time, and the Raiders give up the sixth most fantasy points against opposing running backs.
Delone Carter might be a better RB, but this week he's going up against Atlanta which has a pretty good run defense.
