What kind of trade could I target for RB?

I need help at rb, and trying to figure out a trade in full ppr. I have cousins, Michael Thomas, Fitzgerald, Baldwin, e Sanders, Bell, Lynch, Burkhead, Powell, and p barber. Was thinking of offering fitz and Lynch for a rb, but are they don’t think that will draw much interest. Any ideas what I could give up for a cook or even a Dion Lewis?
