Cordarrelle is extremely droppable / I'd try to trade him. I have him in 2 leagues and will most likely drop him. I figured Teddy would help him out but starting him is just killing me and I'd rather not even have the temptation of starting him.
Buy low RBs: Lacy, Stacy, Ball, Rashad Jennings, Ellington, Ivory, Knowhshon - last 3 are more risky hence the buy low. Depends if you are PPR as well. Ball, Stacy, and Ellington already having bye weeks is a nice plus too. When I look for RBs, I look for guys who have little to no competition. Only guys with competition here are Ivory and Knowshon, but I think they are also clearly the best backs on those teams and will eventually win out / get the goalline carries, which is what matters most.
