Instead of trying to package Colston package up Winslow or Shockey with a lesser RB to get a better RB. You pretty much have 3 top 10 TEs if you play Colston there (which it looks like you do), and you can't start them all. The name recognition of Shockey and Winslow will get you more bites than a deal with Colston. As far as what RB to include, it would depend who you are getting in return but basically I would give them their choice in a lot of situations. They are all average at best, unless it's a ppr league. In that case Bush and Addai's value go up some.
