Would this be a good Fantasy Football Trade?

I would stick with what I have if I were you. You already have two of the top RB's and with Lynch and White you can get inconsitency. Moss is a great player, but has a subpar QB throwing to him (like TJ)! If you do this trade, then you will get more inconsistency, saying that, I would try to get one of those players for somebody else on your team. The guy I would try to get would be Lynch because he will always get his carries and be more consistent than the other 2.
