Devin Bush
Chicago Bears / OFF-BALL LB / Healthy

What the evidence supports
This score forecasts statistical production. Assignment-level execution is not established; use it with role and evidence context, not as a definitive best-player ranking.
Context still needed: coverage assignments; gap responsibility; box and blitz opportunity.
Current performance comes first
Current grade measures qualifying production recorded this season against position peers, with sample adjustment. It is not complete football ability. Without qualifying current evidence, a clearly labeled forecast estimate remains visible. Defensive assignments and individual blocking require additional evidence.
Talent, opportunity, coaching, and availability kept separate
Devin Bush's central production outlook stays at the evidence-based baseline; tracked context affects uncertainty only. This is a downstream production index, not a rewrite of the 76.7 player OVR.
Open context effects and weekly opponent policy
Uncertainty: Opponent scheme, protection, alignment, and likely game script are applied only in weekly forecasts, not silently baked into player OVR.
Position contract: lb-production-context-v1 · coaching gate RESEARCH WITHHELD.
Position coaching driver: Defensive coordinator, base package, coverage assignment, blitz rate, and tackle opportunity.
Season levers: every-down role · package participation · coverage-versus-rush assignment · green-dot role.
Weekly matchup levers: opponent play volume · run rate · middle-field targets · blitz assignment · score state.
Injury and workload levers: sub-package role loss · snap cap · return ramp · teammate tackle vacancy.
Validation state: Public role assignment is not complete enough to convert a DC change into stable individual tackle or coverage production.
Weekly opponent layer: Opponent defense, opposing coordinator, likely score state, venue, weather, and final game designation are recomputed in the weekly projection. They do not rewrite player OVR or this season baseline.

These inputs reproduce the separate 76.7 forecast OVR, not the current-season headline grade. Team impact remains a separately evaluated roster input.
Current-team impact: 77.1. This forecast-heavy value feeds the Chicago Bears roster model after role and availability treatment.
Rank gate: Position-specific sample threshold met. Sample progress: 100%.
Uncertainty: One decimal supports ordering; the range is a heuristic, not a calibrated confidence interval. Typical next-season absolute error is 6.9 points; empirical interval coverage has not yet been calibrated.
Open exact supporting signals
Model receipt
LB production balances tackling, pressure, non-sack disruption, coverage results, breakups, and missed tackles.
The displayed performance component is recency-weighted across qualifying 2026, 2025, 2024 seasons.
Projection uses roster role plus verified prospect evidence when available.
Prospect pedigree and testing are context only after the early-career prior expires; qualifying NFL production is authoritative.
The projection component uses the validated one-season linebacker baseline because the richer candidate failed the 2024-2025 release gate.
Position-specific metrics
Opportunity-neutral indicators
This facet removes role-volume fields where the public data supports it, so targets, touches, and snap share do not masquerade as ability.
