WR/Flex start sit .5ppr

I am playing the top player in my league at 4-1, I am currently 2-3 and in need of a win. I have CEH and Mostert at RBs and Allen Robinson at wr1. My question is wr2 and flex. My options are juju, mecole, justin jefferson, and gibson and gaskin for the flex. I’m currently leaning mecole for a big play and gibson against the giants. Just wanting to get some opinions on who to start cause like I said I could really use a win.

Jefferson hardman Gibson

I’d play Hardman and Jefferson
