Which RB should I trade in my Fantasy league. I have Westbrook, Forte, Barber, and Bush. ?

Barber or Forte will have the best value... Westbrook is a big injury risk and hasn't been consistent, but still gets catches and rushes each game when healthy Bush is a keeper if your are in a PPR league, so I'd check Forte or Barbers schedule going forward and trade whoever has the harder schedule... if I had to pick one, I'd go Barber. Romo will throw more now and Barber is slowing down in the past few weeks.
