Sony Trade Offers

Sony Michel has been fine the last two weeks and so now I am trying to package him with another player to . get an upgrade at RB, Who should I be targeting? 14-man half ppr

My team:

QB: Josh Allen
RB: Dalvin Cook, Sony, Penny, Walton, Mattison
WR: Michael Thomas, Cooks, Dede Westbrook, John Brown, Lazard, Nkeal Harry
TE: Waller

Thanks for any suggestions

Bump. Would love some advice

Question is far too broad. Depends on other team comps, etc.
