Position from each player's primary MLB fielding spot; never-MLB picks excluded. This table is descriptive, not a skill ranking — per-position DVOS isn't reliable at this granularity (split-half ≈ 0 for P/OF, a small-sample mirage for C). The one reliable position cut is Hitter vs Pitcher: drafting hitters (C/IF/OF) above slot repeats (split-half +0.54, the KPI above), but drafting pitchers above slot does not (≈ 0) — so we rank Hitter DVOS and leave pitcher out.

DVOS = Σ (a pick's career fWAR − the expected fWAR for that overall slot), credited to the scouting director SABR lists for that draft. We only attribute years with one unambiguous director on record; years where SABR lists multiple names (handoffs/overlaps) or none are left out, so a director's record here may skip years he was involved in — see the coverage note on the leaderboard. Single drafts are noise-dominated — one star swamps a class — so read the multi-year totals, not any one year. Full method on the DVOS page.
