I'd hang on to Sproles for sure given your league's PPR format. CJ2K + Torrey is an intriguing combo for a top-tier WR. I'd float it for a Julio-type if the Julio owner is thin at RB, but I think you're correct that the most likely deals will involve a 6-12 guy. You also might want to try packaging Torrey + Tate in a deal with Foster's owner, assuming he has a WR you want.
The Foster owner only has him and Murray on his entire roster at RB. No back ups at all for the bye week, and nothing for him on waivers. I've offered him Tate + Chris Johnson for Julio (he would still have Nicks, Boldin, Colston, Hartline, Witten, MBennett at WR/TE).
I also offered CJ2K or Sproles plus Torrey Smith or James Jones in any combination to the Cruz owner (who has Ridley, Joique Bell, and Chris Ivory as his only RBs).
Finally, I offered Sproles or CJ2K plus Decker for A.J Green (owner only has Gore, Mendenhall, Bradshaw, and Vereen, so essentially two available RBs again).
All of these trades have been turned down. I started out offering them CJ2K straight up for the most part and slowly ramped it up, but I'm getting counter offers like Hartline for Sproles and Cecil Shorts for CJ2K.
Since these owners are too dumb to realize how screwed they are, do I just wait a few weeks until it becomes obvious to them? I could probably afford to up the offer again, but they're the ones backed in a corner.
Does anyone think Edelman is going to decline enough to make it worth it to replace the WRs I've offered to sway them?
