Long-career hit
Ronald Darby became a 10-season, 118-game NFL player after going #50. The retained-value model still ranks him 28th of 34 for Doug Whaley because BUF only got 29 of those games.
His retained-value contribution score (opportunity plus quality plus recognition, with related outcomes collapsed inside each bucket) is -2.24. This is a per-pick accountability metric, separate from Doug Whaley's leaderboard composite θ.
Full-career context prevents this from being labeled as a bad talent pick: the negative model score is about retained team value, not whether the draft identified an NFL-caliber player.
The walkthrough below shows which bucket carried the pick: playing time, value quality, or league honors.

Did this pick move Doug Whaley's grade?
The first chart removes the time axis: every Doug Whaley pick is sorted by retained contribution across opportunity, quality, and recognition. Ronald Darby totals -2.24. 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.

How much retained production did Ronald Darby return vs. his slot?
Each mark below is one player's model value above slot. Light gray marks are slot-similar peers: CBs drafted within ±5 picks of Ronald Darby since 2010 (14 players).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.
