Should I pull the trigger on this trade? OR pick up Edwards or Peddington on the waiver?

You don't need Slaton since your RBs are pretty good. But Manning is durable and he is going to pile up tons of ping yards. Edwards has concussion so I'm not sure how it will affect Edwards. And who the heck is Peddington??? I don't think you can get Peddington off the waiver. Maybe Manning is your best option.
