Rest of the year WR flex help

Looking for advice for the playoff stretch for my WR’s. I have Thomas, Adams, and Sutton as my top three WR and currently have Watkins as a 4th. I’m considering dropping Watkins for either Crowder or Conley? I’m currently in 1st place so primarily concerned about the playoff stretch. Thanks for the help

Sorry- it’s a full point PPR league

I’d rank them Watkins, Crowder, Conley … But I don’t love any of them.
