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 (~86), then tapers with age. At 29, Posch sits on 47, past its peak and easing. The blue line is Posch's projected Rating — 51.5 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.
