Below: strengths, watch-points, market-value outlook and the latest transfer news on Baas.

Year-on-year, that's broadly in line with last season (Season 51 → 54). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 76, top 2% of the 51 centre-backs in the Eredivisie. At 23 Baas is still climbing toward his ceiling, and a market index of 97.5 reflects that trajectory.
A career still climbing — Baas is at his peak right now, and the curve hasn't flattened.
3.91 tackles, blocks & interceptions per 90 — solid defensive volume, with 11 clean sheets across 33 appearances. Behind an upper-table side (5th of 18) 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 4 goals and 1 assist — a useful bonus from the back.
With a Rating of 76.2, Baas carries the 1st-highest potential of the centre-backs in the Eredivisie (top 2%). Defensively he reads as solid defensive volume (3.91 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. With this floor already at 23, 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 (~98), then tapers with age. At 23, Baas sits on 97.5, at or near its peak. The blue line is Baas's projected Rating — 76.2 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.
