Where do the Vikings go next for rb?

Here is a list of current free agent running backs below.
Ladell Betts
Willie Parker
Chris Brown
Rock Cartwright
Justin Fargas
Ahman Green
Verron Hayes
Lamont Jordan
Adrian Peterson
Aaron Stecker
Brian Westbrook

The biggest name is obviously Westbrook. He's a huge health risk, but knows the offense is if healthy is a very good 3rd down back. He's a decent blocker and can catch the ball very well I feel he's worth the health risks, but he needs to clear a physical, agree to an incentive rich contract, and stay healthy.

Two other names catch my eye. Justin Fargas who is rumored to be close to signing with the Eagles, and Willie Parker.

I'll cover the possibilities of the Vikings drafting a running back later this month. I personally think they'll go with a veteran listed above and draft a back.
