What do I give up in a trade?

[Booomer]

What you need to know:

14 team league. All TD's 6 pts. PPR=1 pt. All yardage standard scoring. Kick returns and Punt returns are 1 pt every 10 yds as well.
My team:
QB1: Joe Flacco
QB2: Nick Foles
RB1: Darren Sproles
RB2: Jamal Charles
RB3: Fred Jackson (flex position starter?)
RB4: Ronnie Brown
RB5: Johnathan Dwyer
WR1: Percy Harvin
WR2: Brandon Marshall
WR3: Marquies Colston
WR4: Jeremy Maclin
WR5: Randall Cobb (actually ranks as my WR2 on fftoolbox with this type of scoring)
WR6: Titus Young
TE1: Jermaine Gresham
K1: Robbie Gould
Def1: Jacksonville

There is a guy in my league with 3 QB's including Matthew Stafford. I want to target Jay Cutler to trade for. I am looking to give up a WR for him. Marquis Colston or Jeremy Maclins. His WR's are Reggie Wayne and Eric Decker. Then he drops to Mike Williams and Chris Hogan so I think a Maclin or Colston trade would get his interest. But can I get more than Cutler? He also has Peyton Hillis who I would love to sneak away from him in a trade. Not sure how though. And a SF Def would be great to get in a trade.

Thoughts? Help me out!

I can promise you that Cobb wont outscore colston. I think you just offer maclin and your dst for cutler and San fran dst. He boots it try without the dst involved.

Cobb = 39 points in my league
Colston = 14 points
