Once again, hard to say cause I am not 100% sure if he means the lineup in his signature.
But if you do, im playing Ivory over ALL those RBs right now. Addai & Portis might be out, Cadillac blows, and Jacobs will not find it as easy against the cowboys as he did against the Lions.
Again, the only thing is, if you can drop BOTH one D and TJ, maybe I would grab an Ivory, and say a Hart (Indy), and see what happens. If Addai & Brown are BOTH out, then I plug in Hart and Ivory as my starters for next week.
Obviously once Bush & PT are back, then Ivory value slinks back down, but for now he's a great plug in.
