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 (~6), then tapers with age. At 28, O'Neill sits on 3.8, past its peak and easing. The blue line is O'Neill's projected Rating — 29.1 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.
