Big trade help week 3

I’m looking into trading Mike Evans for Metcalf/David Johnson

Would I have to add another piece to that trade? That team I’m looking to trade with is missing Michael Thomas

If that trade goes through I was looking to trade for Kelce since that team is missing CMC and Mostert

That trade I was looking to give Goedart and Hunt/Robinson if I added giving away Bell would that be giving too much? His only other RBs are Dillion and Kerryon
