Am I overthinking? Flex-Torain, Rice, Floyd Goodson?

[Doctor P]

RBs: Foster, J Stew, Torain, Goodson, P Thomas
WRs: Calvin, Boldin, Rice, Floyd

I need 2 RBs, 2 WRs, and a flex. Who do I start this week?

I was thinking I'd start Torain in the flex spot w/Foster and Stewart as my RBs. Do I sit Boldin for Rice or Floyd? While Boldin is frustratingly inconsistent, he does have better stats at home....
