Ppr wr/flex help!

Hello all. I’m pretty wide receiver heavy and i need help choosing my 2 Wide out slots and my flex slots.
Full point PPR here are my options:

Sterling Shepard vs Chiefs (peppered with targets but i am worried about Marcus Peters).
Dez Bryant ( good matchup against philly but injury concerns)
Stefon Diggs
Doug Baldwin ( Should i be worried with his questionable status and corner Desmond Trufant)
Michael Crabtree
Adam Thielen

I need 3 out of these 6. Full PPR. Please help!
Thank you!
