must win week...who to play?

[dreborn]

QB: Freeman/C.Palmer/Rivers
RB1: A.Foster
RB2: Gore
WR1: Welker
WR2: Decker
TE: Brandon Myers
K: Tucker
D: Denver and Cin

Bench: David Wilson, Golden Tate, Mike Wallace, Bowe

I have been loving Denver D lately but they are going up against my starting QB Freeman. I'm thinking start freeman, bench Denver and play Cin since they have great matchup against SD.

Question: who should my flex be? Bowe gets targets but can't catch anything anymore. David Wilson is unproven but could get at least on the board as Andre Brown replacement. Tate is super high risk against the Bears. Wallace has even lost his starting job. I'm in trouble!

any advice? Thanks!
