The New York Jets are evaluating their running back roster as they prepare for the upcoming season, seeking a premier player since Thomas Jones' departure in 2009. Key players include Chris Ivory, Stevan Ridley, Bilal Powell, Zac Stacy, and Daryl Richardson, each with varying levels of success and opportunities to secure a roster spot. The competition among these backs, especially with Ridley aiming to regain his past form, could lead to tough decisions for the Jets before the season begins.
