Output in context · Jubilo Iwata finished 5th of 20 · an upper-table side
0 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 12 appearances. Behind an upper-table side (5th of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 2 goals and 0 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.28 goal involvements per 90, useful for a central midfielder.
Watch points
- Game time. Only 18.5% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 37.5, Sumi carries the 6th-highest potential of the central midfielders in the J2 League of 70 — though on just 12 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
