Read the appearance count in context: Keijzer missed 13 games through injury (inactive, injury) out of roughly 34 this season. The 8 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
0 clean sheets in 8 appearances (0% of games). Keeping that many behind a relegation-threatened side (18th of 18) — a side that concedes more — points to a busy, productive season between the posts.
With a Rating of 50.1, Keijzer carries the 13th-highest potential of the goalkeepers in the Eredivisie of 23 — though on just 8 appearances this season, so the standing rests on a small sample. A rotation minutes keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

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 (~64), then tapers with age. At 26, Keijzer sits on 64.1, at or near its peak. The blue line is Keijzer's projected Rating — 50.1 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.
