UPgrading WR, Which RB to get trade

I am looking to upgrade my WR’s and am trying to buy low in Odel Beckham Jr. The Odell owner need a RB and has given up on him. I have a few extra RB’s to trade so which one should I offer

D. Cook
T. Cohen
C. Thompson

That still leaves me
M. Gordon
M. Ingram.

IT’s a PPR League and start QB, RB, RB, WR, WR, (RB, WR, TE), K, D

My WR’s

T. Hill
A. Brown
K. Golladay
A. Robinson
C. Merideth

Or should I just stay put.
