Full PPR Flex: Robby, Higgins, or Renfrow?

1 Flex Spot in Full PPR

Robby Anderson vs ARI
Tee Higgins vs JAX
Hunter Renfrow vs BUF

Robby is seeing consistent work, so he feels safest, but low ceiling vs ARI. Renfrow should see a lot of targets with Ruggs hurt and Edwards out like last week. Higgins really just a third option on waivers to throw out there, but I feel I shouldn’t buy into one great game.

Thoughts?
