Which QB to pick up with to run with for the rest of the eason?

I have Mariota but I’m not too confident in him going forward.
My options from the waivers are:
D Watson
D Kizer
J Goff

Maybe rank top 3 including mariota please?

Also someone dropped Cam newton in one of my leagues, is he worth picking up or is he done this year

Rest of season…

  1. Mariota
  2. Watson (he’s got Hopkins)
  3. Kizer (He doesn’t have Hopkins)
  4. Goff (his next 7 weeks are a tough schedule, if not for that he’d be #2)
