Ekeler for Watkins?

Thinking of offering Ekeler for Watkins. Not as confident in my WRs as I am my RBs. Both had great week 1, but who is the better rest of season?

My RBs are Kamara, Ekeler, Michel, and Cook. WR are Evans, Cooper, Robbie Anderson, MVS, and Marvin Jones. Full point PPR. 2 FLEX.

Thanks.
