My starting QB's are Eli Manning and Ben Rothlisberger. My WR's I have are Randall Cobb, Marques Colston, Dwayne Bowe, Tavon Austin, and Cecil Shorts. In my league we can start 2 WR's and Flex of WR or TE. My TE is Antonio Gates.
They're fair, but I'm not sure if I'd do either if I was you. Who is your starting QB at the moment and what other WRs do you have? I'd be reluctant to give up Cobb for RGIII, especially in a PPR. Colston for Kaepernick is definitely a fair offer,but I'm concerned about Kaep after averaging 148 yards through these past three games.
