Familia-Castillo is operating at his career peak — the 2025/26 level is the level.
3.84 tackles, blocks & interceptions per 90 — solid defensive volume, with 4 clean sheets across 33 appearances. Behind an upper-table side (6th of 20) 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 7 assists — a useful bonus from the back.
With a Rating of 49.2, Familia-Castillo carries the 43rd-highest potential of the full-backs in the Eerste Divisie of 76. Defensively he reads as solid defensive volume (3.84 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

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 (~40), then tapers with age. At 26, Familia-Castillo sits on 40.3, at or near its peak. The blue line is Familia-Castillo's projected Rating — 49.2 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.
