Jets aim to transform their line into one of the league's best if Olu Fashanu and Armand Membou hit their ceilings. Fashanu protects Fields on the blind side, while Membou brings elite movement for Engstrand's outside-zone game. Inside, Simpson and Vera-Tucker posted top-10 grades, giving New York a sturdier interior and clearer run-punny paths.

Behind Garrett Wilson, pass-catching depth is thin. Lazard's reliability is in doubt, Reynolds and Johnson have yet to establish themselves, and Mason Taylor could shoulder tight-end workload. Justin Fields anchors the fantasy path with rare rushing upside, aided by a scheme that leans into the tush-push for short-yardage punch. Drake Maye's metrics offer context, but Fields remains the true fantasy driver.

Five dark-horse defenses with top-5 upside in 2025 fantasy D/ST rosters are Ravens, Bears, Jets, 49ers, and Commanders. Baltimore leverage elite secondary play with Kyle Hamilton and a ferocious pass rush to generate sacks and takeaways, boosting weekly upside even when matchups are tough. Chicago rebuilt its defensive coaching and talent, emphasizing turnovers with Sweat and brisk secondary play. New York and San Francisco ride cornerstones in Gardner, Bosa, and Warner, while Washington’s soft schedule could fuel a late-season surge.

These units stack upside with realistic weekly floors, balancing negative-point risk against big-play potential. Rostering one of these five can yield week-winning performances in favorable stress spots, while still staying affordable in mid-rounds of fantasy drafts.
