The rare case of having "too many" RBs

I currently own Saquon Barkley, David Johnson, Marlon Mack and Josh Jacobs right now.
I would love to keep Saquon and DJ and was wondering who to keep rest of season between Jacobs and Mack, who both seemingly do not have much of a consistent receiving share.

I was wondering if going after someone like Davante Adams with Mack or Mike Evans with Jacobs would be worth it for my team long term.
I could keep those core guys and roll with any 2 of Hilton, Gallup or McLaurin for my WRs. Its a tough spot but seeing Jacobs on the bench almost seems like a waste.
