2-2 PPR League. Could use advice. WHIR

[hotpocket]

1 pt per reception.
Here's what I have offensively:
QB: Romo
RB: McFadden
RB: Martin
WR: Fitzgerald
WR: Harvin
WR: D. Thomas
Flex: Hartline
TE: Rudolph

BN: Dalton
BN: Ryan Williams
BN: Celek
BN: Brandon Bolden

Now, this week I am obviously screwed with Romo, DMC, and Martin on bye. I feel like I need to make a move, but I'm not sure what. I'm not that high on Fitz, and my RB's have underachieved for the most part. Thoughts?
