Big problem with week 8 lineup

[That Guy]

alright, it's week 8, i've got a few sure starters on the bench and a bunch of RB/WR slots with lots of second tier options and bad matchups :/. not looking good. QB, TE, WR #1/#2, K, DEF are set, but i need 1 more WR, 2 RBs, and a flex (WR/RB) for this week and i'm having trouble figuring it out. there are points on receptions (0.5) and return yards (1 for 20). all names link to yahoo profiles (stats etc).

M. Jones-Drew  (Jac - RB) P   @Phi 71
L. Washington  (NYJ - RB)     @Cle 35
D. McAllister  (NO - RB)      Bal 57
F. Gore        (SF - RB)        @Chi 64

K. Johnson  (Car - WR)    Dal 75
J. Cotchery (NYJ - WR)      @Cle 66
D. Gabriel  (NE - WR)       @Min 40
E. Parker   (SD - WR)       StL 38

Locks:
R. Grossman  (Chi - QB)    SF 67
T. Owens     (Dal - WR)    @Car  58
P. Burress  (NYG - WR)      TB 53 
K. Winslow   (Cle - TE) Q    NYJ 58

A. Vinatieri  (Ind - K) Q   @Den 50
Baltimore     (Bal - DEF)     @NO 105

Not really considering:
C. Pennington  (NYJ - QB) P   @Cle 64
De. Clark      (Chi - TE)       SF 38 

Bye:
C. Portis  (Was - RB)     Bye 73
W. Welker  (Mia - WR) Q   Bye 85
M. Furrey  (Det - WR)     Bye 74

the two somewhat obvious RB coices are facing 2 of the elite defenses in the league :/.

right now i'm leaning towards jones-drew (RB), washington (RB), keshawn (WR), and mcalister (W/R) with a terrible matchup.

any thoughts?
