Jordan Mason stands out as the clearest 2025 league-winner candidate among backups, should Aaron Jones miss time in Minnesota. Mason’s SF stint hinted at explosive efficiency: 120 scrimmage yards per game, ~5.1 yards per carry, and three touchdowns across five games, with heavy volume when the matchup opened. In Seattle, Zach Charbonnet would be the top-handcuff play behind Kenneth Walker III, thanks to superior yards created per touch and a proven track record when given a bigger role. Tyler Allgeier sits behind Bijan Robinson in Atlanta, but his five-year ceiling is enormous if Robinson is sidelined, given his pass-game chops and past 1,000-yard season. In Buffalo, Ray Davis remains a prime late-round stash behind James Cook, who signed a fat extension; Davis logged meaningful snaps and goal-line work in 2024 and could thrive as the lead back if Cook falters. Trey Benson in Arizona represents a high-upside change-of-pace and a potential majority back if James Conner’s durability wanes, thanks to Benson’s speed and breakaway ability. Drafts at pick around 100 could unlock several of these paths to fantasy glory.
