Duffy is operating at his career peak — the 2025/26 level is the level.
2 tackles, blocks & interceptions per 90 — light defensive volume, with 6 clean sheets across 36 appearances. Behind an upper-table side (6th of 24) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 2 goals and 4 assists — a useful bonus from the back.
With a Rating of 33.2, Duffy carries the 7th-highest potential of the central midfielders in the League Two (top 11%). Defensively he reads as light defensive volume (2 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~4), then tapers with age. At 23, Duffy sits on 3.6, at or near its peak. The blue line is Duffy's projected Rating — 33.2 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
