FLEX help need win

Full PPR 12 teams, deep benches and I’m 5-6. I need a critical win this week and I’m off to a good start with J. Williams, however I’m starting Ryan Griffin at TE and am considering Hollister, C. Samuel, Renfrow, bo, or Rico for my flex. Have Hollister starting atm. Thoughts?

I also have N’keal Harry … looks like Dorsett and Sanu are going to miss.
