The 2025 NFL offseason is officially underway, starting with the new league year and a crucial legal tampering window for free agency. While last year's running back market was stacked with stars like Saquon Barkley and Derrick Henry, this year's crop is less glamorous but still features solid players. The top ten free-agent running backs include notable names like Alexander Mattison, who had a productive year with the Las Vegas Raiders despite being a backup. Jordan Mason from the San Francisco 49ers emerged as a key player when Christian McCaffrey was injured, showcasing his potential to attract interest. Other notable mentions include Javonte Williams, who is still recovering from injuries, and Nick Chubb, who has seen a decline in performance. As teams prepare for the draft and free agency, the decisions made will have significant implications for fantasy football enthusiasts and bettors alike.
