WK3 - Watkins or Dem.Thomas in PPR

Knowing Landry gave me nice WR2 numbers on Thurs, and I have M.Thomas as my trophy stud WR1…
WHO do you guys think I should trot out in my third WR slot:
Demaryius Thomas (@BAL)
OR
Sammy “Biscuits” Watkins (SF)

Full PPR

also…what kind of RB value do you think Demaryius Thomas might get in a dynasty league? Is he in the Drake/Ajayi range, or much lower due to age?
