1 WR, 1 Flex for Week 1 -- Full PPR

I need 1 WR and 1 flex for a full PPR league out of Landry, Mike Williams, Cohen, Dion Lewis and Justin Jackson.

Leaning towards Landry at WR, Cohen at flex (my other RBs are D. Cook and Carson) and benching Williams (I also have Julio and Godwin). One of the things making me hesitate is that I have Rivers at QB.

Thanks in advance.
