On long-term talent our Rating reads 33, 108th of 204 of the 204 centre-backs in the J3 League. At 28 Mase is in his prime years, and a market index of 15.2 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
0 tackles, blocks & interceptions per 90 — light defensive volume, with 5 clean sheets across 13 appearances.
With a Rating of 33.3, Mase carries the 108th-highest potential of the centre-backs in the J3 League of 204 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). 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 (~25), then tapers with age. At 28, Mase sits on 15.2, past its peak and easing. The blue line is Mase's projected Rating — 33.3 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.
