Who to Target at RB

My RBs are not great at the moment. I’m somehow 6-4 and need to make some moves

My Team:

RB: Gibson, Taylor, Mostert, Edmonds, Duke

WR: Allen Robinson, Golladay, Woods, Reagor, Marvin Jones

TE: Fant, Goedert

I’ve been thinking about going after Carson or Connor. Who else should I target and what should I give up for them?
