I would go with TJ because I don't think Buffalo is known for their run stoppage however, you need to factor in the possibility of Cedric Benson coming in at some point to take over for TJ. So it may be a good idea to start Cadillac because I don't think his backup will get playing time unless Cadillac goes down with an injury.
So in conclusion, Lovie Smith likes to break up the carries between Jones and Benson, so from that aspect TJ won't help you as much.
