Three out of LT, Hillis, SD, Bradshaw, WHIR

[Rodigee]

This is for a standard (non ppr) 12 team yahoo league. We start 2 RB and have a Flex spot. So I can start three running backs. Here are the options.

LT @ Buffalo
Ryan Mathews/Mike Tolbert vs Arizona
Peyton Hillis vs Cincinnati
Ahmad Bradshaw vs Chicago

I've lumped Mathews and Tolbert together because I don't see myself starting both of them. It would be one or the other depending on if Mathews is healthy. Out of this group, LT looks like the must start because he's on a great running team and has a juicy match up. However, things look hazy after that. How much work will Hillis get with Harrison back? What does Bradshaw do against Chicago's stout defense? Does San Diego return to a balanced offense?
