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 (~89), then tapers with age. At 20, O'Sullivan sits on 75.3, still climbing toward its peak. The blue line is O'Sullivan's projected Rating — 73.8 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.
