RB Needed?

I think the argument for a RB is more about quality vs quantity. Behind Kamara, it’s all a question mark. As good as Ingram has been, how much does he have left? We don’t know. And the backs behind those two? Far from a sure thing. Surely we’ll be able to find some help.We don’t need a star there, but do need another guy who can effectively move the chains and carry a heavier load if called upon.
But we’d also be adding another question mark. There are no difference making RBs walking the streets right now. They are all replacement level. We don’t even know if we will be without Kamara.
