Flex help...Powell or Kearse

My Steelers connor and brown are on bye this so I have Goodwin and John brown as wr1/2 …flex is still up in the air…my options are kearse or blow pow(Bilal powell) …I’m leaning kearse only because how he was used last week but feel they might use Powell more in the passing game…Powell or kearse?

if this is PPR, Kearse by a wide margin imo. I can never get myself to trust Jets RBs

It is PPR thanks for the reply
