Output in context · Renofa Yamaguchi finished 19th of 20 · a relegation-threatened side
0 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 15 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 39.5% of available minutes — needs a settled run to prove the level.
- Defensive numbers. Modest 0 defensive actions per 90 for the position.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 31.9, Okaniwa carries the 11th-highest potential of the centre-backs in the J2 League (top 15%), and he is posting that for a relegation-threatened side (Renofa Yamaguchi finished 19th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
