Drop Lamar Jackson for Ekeler?

I’m the Melvin owner so I know the Ekeler handcuff is important, but I’m worried about dropping Lamar with that sweet schedule and giving my opponents a gem. I have Matt Ryan. I also have Fournette/Yeldon, Mixon, Sony. If Melvin went down I could always start Sony, but I don’t know if Ekeler has too much upside at that point? Full PPR. Thanks for any help!
