Looking for advice for ppr leagues

I’m in a 1 qb 2 rb, 2 wr, 1 te, 2 w/r/t, 1 k, 1 dst, 6 bench league. Who are players to avoid in ppr? Are fliers in Mike Williams and Calvin Ridley usless since they’ll at best be the second or third option on their teams?

I always lean towards best available.
Once the starting RBs start to thin, target pass catching backs (Cohen, C. Thompson, even TyMont should have some value in a pinch in a ppr).
I like Crowder as a later round WR flier in ppr leagues. Keelan Cole should see a bump in usage too. I’d take a flier on Mike Williams this year, even if he’s the 2nd or 3rd option, but I also believe the Chargers will have a good offense this year.
