Eric Rogers’ breakout with the Chargers headlines the preseason, posting a 97.0 PFF overall grade — the top mark among defenders — and leading in coverage (95.3) and run defense (92.6). Chicago-born undrafted players have a real platform to push for roster spots, but Rogers’ play makes a compelling case for immediate IDP fantasy attention and a possible late-season rise in snaps if he maintains his form.

Patriots rookies Will Campbell and TreVeyon Henderson plus undrafted Efton Chism III are turning heads in New England, flashing enough to spark Week 1 fantasy chatter. Campbell’s strong run-blocking and pass protection grades, Henderson’s explosive touches, and Chism’s route-running and contested catches paint a clear path to early involvement, especially in New England’s dynamic offensive scheme which could vault them into valuable depth-chart roles for fantasy managers.

Elsewhere, Gunnar Helm, Grey Zabel, Willie Lampkin, Andrew Mukuba, Jay Higgins, Kenneth Grant and Austin Booker emerge as notable preseason standouts, underscoring the value of chasing sleepers who could contribute in 2025. If these trends hold, fantasy players might add affordable, high-upside pieces late in drafts, while roster decisions in late August could tilt the depth charts toward these names as the regular season approaches.
