Mixon for Thielen? Half PPR

My RB’s:

Ezekiel Elliott
Joe Mixon
Sony Michel
Tevin Coleman
Devin Singletary
Matt Breida

My WR’s:

Cooper Kupp
Marquise Brown
Robby Anderson
Desean Jackson
Will Fuller
Mecole Hardman

I lost Antonio Brown. I tried to package Marquise Brown and Sony Michel for Thielen but I don’t think that will pass. Was thinking of upping the offer to Mixon. The team with Thielen is in last place and missing Saquon Barkley. They are currently starting Royce Freeeman and Adrian Peterson. So RB desperate to say the least.
