Below: strengths, watch-points, market-value outlook and the latest transfer news on Colwill.
Judged on this season alone, Colwill graded 26 — a workmanlike campaign that ranks 29th of 63 of the 63 defensive midfielders in the League One, on 5 goals, 2 assists and 2.964 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 18 → 26). Across the 3 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 50, top 7% of the 63 defensive midfielders in the League One. At 21 Colwill is still climbing toward his ceiling, and a market index of 28.1 reflects that trajectory.
A career still climbing — Colwill is at his peak right now, and the curve hasn't flattened.
2.96 tackles, blocks & interceptions per 90 — moderate defensive volume, with 8 clean sheets across 39 appearances. Behind a title-challenging side (2nd 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 5 goals and 2 assists — a useful bonus from the back.
With a Rating of 50.3, Colwill carries the 4th-highest potential of the defensive midfielders in the League One (top 7%). Defensively he reads as moderate defensive volume (2.96 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow. With this floor already at 21, the ceiling gets tested by a step up in level — one to track.

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 (~31), then tapers with age. At 21, Colwill sits on 28.1, still climbing toward its peak. The blue line is Colwill's projected Rating — 50.3 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.
