Mims is pitched as Denver’s high-upside sleeper, with preseason usage suggesting a real path to involvement behind Sutton. His speed and college production profile keep him squarely in the late-round conversation for fantasy managers chasing weeks-to-go upside.

Mims Jr. delivered a late-season surge as Denver’s clear second option, highlighting elite efficiency (4.25 yards per route run) and high target share in a seven-game stretch. His movement from a deep threat to a versatile outside-slot mix increased his weekly upside, with a role that could grow as Denver’s offense stabilizes behind Payton’s system and a rising QB performance.

Marvin Mims Jr. is a high-upside sleeper for 2025 in Denver if he earns more routes and consistent targets. He’s shown that when on the field his results are efficient, suggesting a path to spike weeks in best-ball formats should opportunity increase, aided by the Broncos’ evolving passing framework.

Mims brings legitimate big-play potential, aligning with Nix on the boundary for explosive chances. His speed and route-running add a high-ceiling dimension to Denver’s passing attack, especially in spread looks where timing and space create yardage and scoring chances.

Mims is flagged as Denver’s breakout candidate whose upside dwarfs the cost, especially if Denver’s aerial attack comes alive in 2025. Draft bible projections place him as a key late-round flyer with a path to core- WR status behind Sutton, driven by efficiency and volume growth as the Broncos develop a potent air game.
