Judged on this season alone, Graaff graded 10 — a workmanlike campaign that ranks 14th of 23 of the 23 goalkeepers in the Eredivisie, on 6 clean sheets across 36 appearances.
Year-on-year, that's a clear step up on last season (Season 2 → 10). Across the 4 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 73, top 9% of the 23 goalkeepers in the Eredivisie. At 21 Graaff is still climbing toward his ceiling, and a market index of 84.1 reflects that trajectory.
Graaff is operating at his career peak — the 2025/26 level is the level.
6 clean sheets in 36 appearances (17% of games). Keeping that many behind a lower-table side (15th of 18) — a side that concedes more — points to a busy, productive season between the posts.
With a Rating of 73, Graaff carries the 2nd-highest potential of the goalkeepers in the Eredivisie (top 9%), and he is posting that for a lower-table side (PEC Zwolle finished 15th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. A near ever-present keeper carrying the gloves this season. 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 (~93), then tapers with age. At 21, Graaff sits on 84.1, still climbing toward its peak. The blue line is Graaff's projected Rating — 73 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.
