Stewart, Moats, or Morris?

[disturbedlogic]

I play in a Dynasty League where the free agent list is barren. I have both DeAngelo Williams and Jonathan Stewart; in most cases sadly have to start both. Never like starting two running backs on the same team but have very little choices. I had Slaton but he’s now on the IR. My other options are Ryan Moats (vs. Seattle) and Sammy Morris (vs. Carolina). Should I start Stewart over Moats or Morris?
