August updates expose a loaded 2025 rookie RB class with Ashton Jeanty, Omarion Hampton and TreVeyon Henderson leading the charge. Hampton and Henderson profile as high-upside the moment injuries or depth-chart shifts strike, while Jeanty’s preseason burst suggests a clear path to additional work in Vegas. RJ Harvey and Kaleb Johnson sit just behind, poised to mix in behind Denver and Pittsburgh backs respectively. Jaydon Blue and other Tier 3-4 backs offer late-round leverage in dynasty and best-ball formats as rosters settle. The piece emphasizes dynamic backfields, preseason cues and dynasty sleepers, plus ARB-like upside in Aug updates and ADP signals that shift as teams finalize their rosters.
