Biggest surprise: Chris Ivory. The undrafted rookie running back saved the Saints from a potentially catastrophic situation. With a preseason injury to Lynell Hamilton and early-season injuries to Pierre Thomas and Reggie Bush, the Saints were desperate for help at running back. They brought in veterans Julius Jones and Ladell Betts, but neither did much. Instead, it was Ivory who stepped up and gave the Saints enough of a threat in the running game to keep opposing defenses from loading up on the passing game. Ivory probably has secured a spot in the running back rotation for the foreseeable future, though he will miss the playoffs with a foot injury.
