B Jacobs or W McGahee for J Witten?

[Jon FLA]

should I do it? This guy wants to trade J Witten and possibly AJ Green for a RB. He had F Jones...

Problem is I had J Charles, but I also have R Rice, B Jacobs, and W McGahee.

For TE's I got K Winslow and S Chandler

WR's D Bryant, S Johnson, M Manningham, B Lloyd

Should I offer a different player or what?

HIS QBs T Brady, M Hasselback
HIS WRs G Jennings, W Welker, AJ Green, E Doucet, Austin Collie
HIS RBs L McCoy, F Jones, D Karim

Im thinking I might not trade him and watch him get destroyed on Brady's bye week..
