We hold a single season for Duncan, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 6, 14th of 14 of the 14 goalkeepers in the A-League. At 33 Duncan is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.2 reflects that trajectory.
2 clean sheets in 11 appearances (18% of games). Playing behind an upper-table side (4th of 12) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.
With a Rating of 5.7, Duncan carries the 14th-highest potential of the goalkeepers in the A-League of 14 — though on just 11 appearances this season, so the standing rests on a small sample. A rotation minutes keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
Generated from Field Insider's rating model · AI-written analysis to follow.
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 (~1), then tapers with age. At 33, Duncan sits on 0.2, past its peak and easing. The blue line is Duncan's projected Rating — 5.7 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.
