Should I trade AJ Green or Dez Byrant for Lynch.

My team
QB: Brady
RB: Gore, Daniel Thomas, Starks, Ridley, Morneo, Micheal Bush, and Kendall Hunter
WR: Greg Jennings, Hakeem Nicks, Dez Byrant, and AJ Green

I don’t plan on ever starting AJ Green over my other WR and would like to get value for him. I know the other team will accept Lynch for Green or Byrant. I think Bryant has more upside and a easier schedule, I also think Green has a difficult schedule for the rest of the season. Should I make the trade, I need RB help and Lynch is starting to look good. Or should I try to trade Green or Byrant for a different RB?
