RB problems w/ D Williams & B Jackson, need trade advice

[kneedtowin]

Williams has been a bust thus far. Should I ride the storm and keep starting him?
Jackson did not look impressive
So I need a solid RB. I have good WRs which could help w/ a trade.
I have Vick but he obviously won't be starting next wk and w/ Ben still suspended wk 4, I won't have a qb that week.

I figured I would just pick up a qb in wk4. Or should I try to trade him and hope someone is dumb enough...
Most importantly what kind of trade should I make for a consistent running back? Team in sig.

Anyone have WR problems and extra RBs?
