Kenan Allen for Jay Ajayi

I need some RB help. I have Mark Ingram, Joe Mixon, Marlon Mack, and Darren McFadden (fingers crossed he becomes the #1 option.) I have Julio, Thielen and Kenan as my WRs. Do I trade Allen for the Ajayi upside in Philly. The team i’m trading with has a desperate need for a stud WRs. (I’m currently 4-4)
