Dynasty Trade Proposal

[APAP]

His Vincent Jackson and Knowshon Moreno for my Steven Jackson in a dynasty league. My RB's are weak so giving up SJax isnt my favorite thing right now, but is this fair value for him??? I am in a bit of rebuilding mode and my teams not very good, but right now Jackson's one of my top players.

Roster:

QB: Donovan McNabb, Jay Cutler, Seneca Wallace
RB: Steven Jackson, Darren Sproles, Felix Jones, Willie Parker, Donald Brown, Michael Bush
WR: Wes Welker, Bernard Berrian, Devin Hester, Anthony Gonzalez, Josh Cribbs, Jacoby Jones, Jeremy Maclin
TE: Vernon Davis, Todd Heap
D: SD, BUF
K: Rob Bironas, Jay Feeley
