J. Simpson is a 29-year-old central defender at Leyton Orient, rated 28 overall by Field Insider's model, ranking 363rd of 482 in the League One. An experienced operator, he has been a rotation option this season (55.6% of available minutes). His defensive output reads 3.56 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Simpson.
Judged on this season alone, Simpson graded 21 — a workmanlike campaign that ranks 42nd of 89 of the 89 centre-backs in the League One, on 6 clean sheets and 3.559 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 10 → 21). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 28, 64th of 89 of the 89 centre-backs in the League One. At 29 Simpson is in his prime years, and a market index of 9.5 reflects that trajectory.
A career still climbing — Simpson is at his peak right now, and the curve hasn't flattened.
3.56 tackles, blocks & interceptions per 90 — solid defensive volume, with 6 clean sheets across 35 appearances. Doing that for a lower-table side (20th of 24) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 2 goals and 1 assist — a useful bonus from the back.
With a Rating of 28, Simpson carries the 64th-highest potential of the centre-backs in the League One of 89, and he is posting that for a lower-table side (Leyton Orient finished 20th of 24) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as solid defensive volume (3.56 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).

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 (~17), then tapers with age. At 29, Simpson sits on 9.5, past its peak and easing. The blue line is Simpson's projected Rating — 28 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.
