Need Flex Help- Golladay, White, Deebo, Mattison

This is a tough decision with these guys all closely ranked. Kenny G gets the nod via the ballers and PFF rankings. I made the mistake of benching golladay last week but it didn’t stop me from getting the win. If I do pivot, James White and then Deebo would be my choices. I’d like to know your opinions. This is a .5 PPR league. Thanks!
