Mixon Offered Need RB

Full PPR. Someone came to me offering Mixon for Kerryon and Darren Waller. In a vacuum I don’t like it but for my current situation I might have to take it…

My RBs:
Kerryon
Sony
Singletary
Coleman

I also have Kelce on top of Waller… What do you guys think of this trade? He also has Melvin Gordon and would it change anything for you if I could get him to throw in Gordon as a stash?
