Output in context · JEF United Chiba finished 19th of 20 · a relegation-threatened side
2.65 tackles, blocks & interceptions per 90 — moderate defensive volume across 2 appearances. Doing that for a relegation-threatened side (19th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight.
Watch points
- Game time. Only 2% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 22.6 overall — below regular-starter level. Defensively he reads as moderate defensive volume (2.65 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
