HELP...Rest of Season

I'm sitting in a league where L. Timmons let me down big time! I finally dropped him...I need help

Scoring - Solo - 1, Assist - .5, Sack/Int - 3, Fumble Forced/Rec - 1, TD - 6, Sfty - 2, PD - 1, Block - 2

We start 1 DL, 2 LB, 1 S, 1 CB

Can only roster 2 DL, 3 LB, 2 S, 2 CB

My current roster is

DL - Charles Johnson (CAR), JPP (NYG)
LB - D. Butler (SD), J. Farrior (PIT), S. Tulloch (DET)
S - L. Landry (WAS), G.Wilson (BUF)
CB - J. McCourty (TEN), K. Arrington (NE)

Here are the available FA's in my league. Should I drop anything I have for any of these for the rest of the season outlook?

LB - D.Washington (ARI), D.Hawthorne (SEA), D. Levy (DET), J. Chaney (PHI), Aldon Smith (LB/DL eligible), J. Mayo (NE), L. Timmons (PIT), L.Woodley (PIT)

DL - Aldon Smith (DL eligible), M.Johnson (CIN) (DL Eligible)

CB - DJ Moore (CHI), T. Jennings (CHI)

S - A.Rolle (NYG) (I just dropped him for Landry because of the bye week issue), D.Manning (HOU), E. Smith (NYJ)

Please help, I'm 2-4 in my league, I'm pretty solid on offense, just haven't scored much out of my LB's which have cost me games. I've lost all 4 games by less than 10 points each time. Lost last week by 2 points. I started Timmons and Chaney and had a total of 1 point from them combined.

I'd drop Butler and Farrior for Mayo and Washington ROS. For this week, I'd drop Butler for Washington since Mayo is on bye.

Thanks GURU.

Should I keep Farrior and play him this week? Or go ahead and get Mayo just in case?

If I keep Farrior one more week, which 2 would you start out of Farrior, Tulloch, Washington this week?

Keep Farrior this week and start Farrior and Washington (assuming Timmons stays outside). Otherwise, drop Timmons and pick up Mayo.
