Better Waiver Add Hardman and Robinson? (1 Viewer)

I still have Hardman and Robinson available in my league.  Should I drop Josh Gordon or Terry Mclaurin to pick one of them up? I was thinking of dropping Gordon since his value seems to have taken a hit with the addition of Antonio Brown.  I also have Gallup who is gonna be out for a few weeks. 

Half Point PPR.

Gordon is third fiddle on the Pats WR's.  The problem with Hardman and Robinson is that their numbers could really vary widely between them and Watkins from week to week but if you want upside and not floor than I'd do it.  You can always drop them in a few weeks when Tyreek comes back and pick up whomever is then the flavor of the day. I'd keep McLaurin as he has better season long floor.
