Game and Season Unit Ratings

Each small dot is one offensive or defensive game rating, arranged in the order played. For completed seasons, the short bar is that season’s average game rating. Both dot and bar values are labeled on a percentile scale. For 2026, the bar is the Bayesian estimate, while the outlined circle is the empirical games-only mean. Labeled background bands show each head coach’s era.

Purdue individual offense and defense game grades by seasonEach small point is one game. Horizontal bars show completed-season means and the Bayesian estimate for 2026. The outlined 2026 circle is the empirical games-only mean. Alternating labeled bands identify head-coaching eras.Hazell · ’14–’16Darrell Hazell, 2014–2016Brohm · ’17–’22Jeff Brohm, 2017–2022Walters · ’23–’24Ryan Walters, 2023–2024Odom · ’25–’26Barry Odom, 2025–2026offenseGame-grade percentile · higher is better9975502512014 Week 1: Purdue vs. Western Michigan · W 43–34;

How to read 2026

The current-season estimate intelligently blends last season with new data.

The 2026 estimate is a Bayesian weighted average of normal-score Z-values. The 2025 season mean counts like 8 games of prior evidence; each completed 2026 game counts once. The result is then translated back to the 0–100 percentile scale.

2026 Z = (8 × 2025 mean Z + games played × 2026 mean Z) ÷ (8 + games played)

Season record

Every annual grade and coach

Retrospective rows average the available single-game grades in normal-score space. The result is shown as a percentile. Roughly speaking, a 95th-percentile season corresponds to about the eighth-best team in a 160-team field.
