QBERT 2026: A Revised Quarterback Rating System Aimed at Isolating Individual Performance

Core Update – What QBERT 2026 Introduces
The QBERT model, first released in 2025, has been overhauled for the 2026 season. Its purpose is to rate every NFL quarterback who has thrown a pass since 1950 on a common statistical footing and to supply those ratings to ELWAY, the author’s season-long projection engine. The new version adds an interactive tool for comparing quarterbacks across eras and incorporates the most recent data available.
Methodological Changes
- Expanded historical sample – The coefficient fitting now uses advanced-statistic data from 2006 onward, rather than the 2016-2024 window used previously. This broader sample balances the recent “mobile-QB” era with earlier periods that favored pocket passers.
- Reduced touchdown weighting – The valuation of passing touchdowns has been cut by roughly 50 percent, shifting credit toward first-down production and other predictors of long-term scoring.
- Sneak-play adjustments – Sneak touchdowns now receive a penalty term, and credit for rushing touchdowns is reallocated to non-sneak runs.
- Removal of game-script variables – Credit for quarterbacks who built early leads has been eliminated to keep QBERT focused on quarterback-specific contributions.
- Interception handling – Interception rates are regressed toward an expected league average until several seasons of data establish a reliable personal rate.
- Statistical injury modeling – Injury risk is derived from four rules: past injuries predict future injuries; career longevity suggests durability; age raises risk; and a high sack rate increases risk. The author estimates that, in any given week, 4-5 percent of healthy starting quarterbacks become unavailable.
Data & Statistics
- Sneak-play impact – Jalen Hurts and Josh Allen together account for 51 sneak-play touchdowns, prompting the new penalty.
- Signal boost for ELWAY – The combined revisions are projected to raise the predictive signal supplied to ELWAY by 10-15 percent.
- Injury-risk correction – The revised injury model raises the weekly unavailability estimate from roughly 2-3 percent to 4-5 percent for healthy starters.
Impact on Rankings
The updated weighting favors pocket passers, lifting players such as Matt Stafford in the historical ratings. Josh Allen remains the top-ranked quarterback, while Brock Purdy receives a notable boost, reflecting the model’s reduced reliance on team context. Patrick Mahomes is projected to need a “re-establishment” period before regaining his prior rating.
Official Explanation
By expanding the data window, de-emphasizing touchdowns, and removing game-script credit, the system seeks a more robust cross-era comparison. The statistical injury framework replaces the prior hand-curated grades, addressing an identified under-estimation of weekly injury risk.
Conflicting Reports & Gaps
The description of QBERT’s improvements relies on internal validation; no external third-party assessments are cited. Consequently, the alignment of the new touchdown weighting or injury model with league-wide outcomes remains unverified.
What’s Next
The ELWAY projection model, built on the refreshed QBERT ratings, is slated to launch soon. Both QBERT and ELWAY will receive weekly updates throughout the 2026 season as new game data become available.
