Free Agent market is loaded with RB's. Draft is going to be flooded with mid/late round RB's with younger legs that'll come cheaper.
I see this ending no differently than the folks that were waiting years and years for Michael Bush's new home
If you're hoping for a signing as a 3 down back like Lamont Jordan, you're going to be very disappointed.
I looked through this thread. Saw not a single mention that Gerhart stunk. I do think he's a solid backup RB capable of a carrying a heavy load when called upon. I think his best case scenario will be being paired with a back like Lamar Miller/Ellington and could be used as a pass blocking back (and fill if injured).
