Not sure what to do with my lineup

Full PPR
It’s a 1 RB, 2WR, 2FLEX league…

Definite starts:
Conner, CEH, Calvin Ridley

I need 2 more of the following but at least 1 needs to be a WR:
Boston Scott
DJ Chark
Kenyan Drake
Diontae Johnson

Suggestions?

Johnson should play so he’d be my WR choice and Drake. Better floor for drake as compared to Chark and he’s been limited in practice.

I’d go Chark and Drake, Chark has been hurt but so has Johnson and there’s a lot more weapons in Pitt than Jacksonville so it’s not like they have to go back to Johnson now that he’s back.
