Loaded at RB

I’ve got 5 RB1s and can only start 4 (drafted RBs in the first 4 rounds and we have 2 Flex spots). We’ve got an 8 team 1/2 PPR league, btw…

My RBs are: Zeke, Jacobs, Sanders, A. Jones, Jonathan Taylor, David Montgomery, and Swift.

Kind of weak at WR, I have: Amari, Kupp, Chark, and AJ Green.

Should I try to trade for a WR? If I could get Julio or Ridley for one of my RB1s which one should I trade away? Or should I try to trade one for CMC (e.g. Jacobs for CMC)?
