Who has the most upside of these backs?

[CitySushi]

I'm in a 12 team league, and it's pretty slim pickings for a backup RB. Who should have the most upside this year?

Dexter McCluster
DeMarco Murray
Montario Hardesty
Marion Barber
_________(fill in the blanks)

Popular guys like Kendall Hunter, Ben Tate, Delone Carter, etc, have been taken already. Thoughts would be appreciated.

Barber's probably the most proven. The best one now is Thomas Jones, if he's available.

I like Mccluster he has some hands. And Charles is gone for the year with a torn ACL.
