Not to mention Brown has no running instincts. Just a physical specimen.
Kubiak would probably like Daniel Thomas, though, unfortunately. Shanahan would too (though I can imagine him trying to get the GM to trade for Helu, Jr. ugh). There are times when Thomas has a bit of that Foster/Forte thing to him. Problem is he has poor instincts, too. He always just cuts back whether anything is there.
James Starks is a FA but I think someone will end up overpaying for him. Hopefully not us. I realize he's productive but I just honestly don't like watching him run. Sort of awkward and plodding, though he's faster than he looks.
Here's a list of guys who'll be FA running backs:

I look at that and only one word comes to mind:
DRAFT.
