A lot of NFL backfields will look different in 2015. We've already seen DeMarco Murray and SportingCharts.com, of the running backs with 50-plus carries in 2011, Ridley's fumble rate ranked 27th, tied with a torn ACL and MCL, which ended his season early.

But at this point in time, Ridley makes for the perfect low-cost, high-upside signing. He's proven to be effective with a large ground-game role. He's not a fumbling machine like many believe he is. He's a good, solid running back, and when you look at depth charts around the NFL (Atlanta, Tennessee, Dallas, Arizona, San Diego, Tampa Bay, Jacksonville), you have to wonder why team's aren't making the move to sign him.

If nothing else, even if he's not 100 percent at the start, you know he's better than Trent Richardson.
