What RBs do I give up on and trade for some WR depth?

10 team league
1/2 PPR
1QB 2RB,3WR,1Flex, 1TE

QB- Cam
RB- Melvin, Cook, kerryon, Penny,Lynch,Derek Henry, Phillip lindsay, Ingram(suspended),
WR- Michael Thomas, M. Evans, Sammy Watkins, Hogan
TE- Burton

So I have tons of RBs… This is a auction keeper league so my RBs do have increased value a little bit as I can keep anyone but cook, Melvin or Lindsay for around $15 next year. But saying that.

I’m just not sure who to offer up… lynch is my first option but he has been getting more points than Henry or Penny the first 2 weeks…

So who would you deal for a WR?
