Kevin’s 2025 NFL sleeper list centers on four late-round bets with clear paths to upside in best-ball formats. Marvin Mims Jr. lands as Denver’s outside option if he earns more routes and targeted volume, turning efficiency into spike-week potential. Isaac Guerendo sits behind Christian McCaffrey in San Francisco and thrives as the prime contingency if McCaffrey misses time, offering strong late-round value. Brenton Strange in Jacksonville profiles as a slot/inline mismatch with room to command targets as Engram’s role remains uncertain. Matthew Stafford proves a steady floor play in Los Angeles, where the supporting cast and McVay’s scheme could push him toward a multi- TD, 4,000-yard season if he remains efficient. The piece stresses that true late-round gold comes from players with traits plus favorable situations, not just pedigree.
