R.O.S. LBs

I keep 4 LBs on my roster and play two each week. Presently sitting with D. Jackson, D.J. Williams, P. Willis, and C. McCarthy. Playoffs run weeks 15-17. Notables available on the wire are Maualuga, Thomas Howard, C. Barwin, Sean Lee and D. Ware.

Given the following schedules for weeks 15-17 which four would you keep going forward?

Jackson - Ari, Balt, Pitt (seems like a lock)
Williams - NE, Buf, KC (LB1 but crap schedule except for wk 17)
McCarthy - Indy, Jax, Hou (crap schedule but a BEAST lately)
Willis - Pit, Sea, SL (worried about the injury)
Maulaluga - SL, Ari, Balt (fairly solid plus a great schedule)
Howard - SL, ari, Balt (same as Rey)
Barwin - Car, Ind, Ten (good spec but crap schedule)
Lee - TB, Phi, NYG (I like wks 15 and 16)
Ware - TB, Phi, NYG (I like wks 15 and 16)

What say you guru? You help get me this far, now take me all the way!

I'd stick with the 4 studs you have. Big players tend to make big plays down the stretch.
