3 clean sheets in 19 appearances (16% of games). Keeping that many behind a relegation-threatened side (20th of 20) — a side that concedes more — points to a busy, productive season between the posts.
With a Rating of 50.1, Heerkens carries the 18th-highest potential of the goalkeepers in the Eerste Divisie of 26, and he is posting that for a relegation-threatened side (Jong Ajax finished 20th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. A rotation minutes keeper carrying the gloves this season. At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, 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 (~41), then tapers with age. At 20, Heerkens sits on 34.9, still climbing toward its peak. The blue line is Heerkens'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.
