Should I propose this trade?

I wouldnt do this, because I dont think your recievers are horrible. Wayne is def a good receiver and TJ and Walter are solid #2's. They arent world beaters by no means but they dont s..k!!!! I would keep Grant for the RB depth. Plus he will do better than he did last year and could be a real steal of the draft since he has been going so late (Ill guess you got him in the 4th or 5th round.). Plus Vincent Jackson is good but is he really all that much better than T.J. or Walter? I wouldnt bet a #1 running back on it.
