The 2025 NFL offseason has already seen some significant running back movements, with Najee Harris making waves by joining the Los Angeles Chargers. Harris, who had a successful stint with the Pittsburgh Steelers, is expected to thrive with a more robust offensive line and a clear path as the primary back. Kenneth Gainwell takes his place in Pittsburgh, likely entering a split backfield with Jaylen Warren. Meanwhile, AJ Dillon's transition to the Eagles may not yield much fantasy relevance given his competition for touches. Rico Dowdle's move to the Panthers positions him alongside Chuba Hubbard, but he may not be the lead back. Javonte Williams and Miles Sanders' arrival in Dallas complicates the RB picture, as both have struggled with consistency. Raheem Mostert's signing with the Raiders could see him in a committee role, while Alexander Mattison's move to Miami suggests a less favorable position behind De'Von Achane. The offseason also features Jordan Mason's switch to the Vikings and Elijah Mitchell's arrival in Kansas City, which could challenge established players like Aaron Jones and Isiah Pacheco. As these changes unfold, fantasy implications will ripple across rosters, making for an exciting yet unpredictable 2025 season.
