Hate My Team... Flex/WR help

[undrgrnd]

My team has been rocked by injuries and such - I'm trying to salvage what I can from my season and need some help on who to start at flex and WR

My team is below (team in sig in my other league) bolded are my current starters:

14-team PPR yahoo league.

QB: Rivers
WR: Wayne, Ocho, MThomas, Dez, and MWilliams (SEA)
RB: Matthews, BJackson, RWilliams and RBush
TE: Carlson
Flex: Shockey
K: Rackers
D: SD

Now I'm curious if I should keep starting Shockey at Flex or move Sticky Ricky into the Flex spot?
Also should I start Mike Thomas at WR or start Mike Williams (SEA)? Awful choices I know, but it's really all that's left.

Thanks in advance.

you might be best off looking at the waiver wire and getting guys that have favorable matchups against crappy def for the week
