Did this pick move Brad Holmes's grade?
The first chart removes the time axis: every Brad Holmes pick is sorted by retained contribution across opportunity, quality, and recognition. Sione Vaki totals -0.32. The second chart breaks that same contribution into the seasons when the evidence arrived. Opportunity and quality can move separately, which keeps high-snap, low-AV profiles from looking cleaner than they are.

Light gray marks are slot-similar peers: SAFs drafted within ±5 picks of Sione Vaki since 2010 (1 player).The score is the retained production/value bucket from the pick-residual model: on-team AV plus AV-rate quality, adjusted for draft slot, position, and era. Opportunity snaps and league honors are excluded.

Cumulative value over time
Year-by-year running totals since draft. Left axis = games started. Right axis = honors (Pro Bowl / AP1 / AP2). Pre-2013 picks have no games-started line because that comes from per-game snap counts (not available for older players). Honors extend back to 1980.

How to read this
The current model groups outcomes into three buckets: opportunity (games, starts, snap-z), quality (on-team AV, AV/snap quality when available), and recognition (Pro Bowl, AP1).
Season rows show full-career context across every team. The draft-credit cards above contain the team-specific totals used for GM accountability. Snap-z is position/year-normalized playing time; AV/snap is shown as AV per 1,000 snaps where snap evidence exists.
AP2, full-career AV, HOF, and All-Decade are displayed as context only. They are not active outcomes in the current θ model.
Pre-2013 playing-time rows may show "—" where weekly snap evidence is unavailable; AV/snap quality is snap-era only.
