Ertz Trade HELP!

Should I accept trade?

I receive Ertz I give Marvin Jones Jr. I already have Waller and my other WRs are Davante Adams, Larry, DK, Robby Anderson. It’s a 1/2 ppr 14 man league so I could use Ertz or Waller as trade bait down the road need be. But just trying to decide who is better to have rest of season MJJ or Ertz?
