The running back market isn't laden with many big names.
Maurice Jones-Drew headlines the list—as far as having a big name goes—along with Darren McFadden and Knowshon Moreno. We have already discussed Donald Brown, but there is another low-flying option who could be a big boon to needy teams.
Rashad Jennings had a marvelous season in 2013, more than filling McFadden's shoes when the latter was predictably out with injury for the Raiders.
Jennings averaged 4.5 yards per carry and scored six touchdowns. McFadden averaged just 3.3 yards per carry.
This has happened with Jennings before—he looked great as Jones-Drew's backup in Jacksonville for a couple of seasons—but he had a miserable contract year with the Jaguars, which is why he landed in Oakland as a backup.
The downside here is Jennings' age. At 28, he is already past his prime as a running back.
Given he doesn't have a lot of mileage on those legs, however, Jennings could become the next Fred Jackson of the NFL. The Buffalo stalwart has had a late-career renaissance, much of which has come north of 30 years old.
