Below: strengths, watch-points, market-value outlook and the latest transfer news on Curtis.
Judged on this season alone, Curtis graded 18 — a workmanlike campaign that ranks 41st of 83 of the 83 full-backs in the League Two, on 6 clean sheets and 3.721 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 7 → 18). Across the 3 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 33, top 8% of the 83 full-backs in the League Two. At 20 Curtis is still climbing toward his ceiling, and a market index of 8.4 reflects that trajectory.
A career still climbing — Curtis is at his peak right now, and the curve hasn't flattened.
3.72 tackles, blocks & interceptions per 90 — solid defensive volume, with 6 clean sheets across 24 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 1 assist — a useful bonus from the back.
With a Rating of 32.9, Curtis carries the 6th-highest potential of the full-backs in the League Two (top 8%). Defensively he reads as solid defensive volume (3.72 tackles, blocks & interceptions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output 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 (~10), then tapers with age. At 20, Curtis sits on 8.4, still climbing toward its peak. The blue line is Curtis's projected Rating — 32.9 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.
