With a Rating of 27.4, Turnbull carries the 89th-highest potential of the central midfielders in the Major League Soccer of 149 — though on just 12 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.56 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 (~14), then tapers with age. At 28, Turnbull sits on 8.5, past its peak and easing. The blue line is Turnbull's projected Rating — 27.4 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.
