Every play is a data point. Every rep tells a story.
PPI stands for Play-by-Play Impact. Itβs a performance grading system that measures how much impact a player has on each individual play β and how that impact accumulates over time.
The goal is to provide a consistent, position-neutral way to evaluate players, regardless of scheme, system, or team. Every action that affects a play β whether it's a block, a read, a mistake, or an explosive effort β is categorized, weighted, and tracked.
PPI groups every outcome into one of ten core evaluation categories that apply across all positions:
Pre-Snap Success:
The player aligned correctly and fulfilled their assignment before the snap.
Pre-Snap Failure:
The player misaligned or failed to execute their pre-snap responsibility.
Post-Snap Success:
The player executed their job properly after the snap, within their assignment.
Post-Snap Failure:
The player missed their assignment or made a mistake after the snap.
One-on-One Win:
The player beat their direct opponent in a 1v1 matchup.
One-on-One Loss:
The player was beaten by their direct matchup on the play.
Elite:
The player made a standout, high-impact play that exceeded expectations.
Deficient:
The player made a critical error or performed well below expectations.
Positive Momentum Impact:
The play contributed to a driveβs success, a big moment, or field position swing.
Negative Momentum Impact:
The play killed momentum β like a penalty, turnover, or blown coverage.
PPI is almost completely outcome-driven. This ensures the highest quality of data while minimizing bias.
Currently, The Player Repo tracks over 70 outcome criteria β ranging from coverage wins, block wins, and explosive gains, to drive-killing mistakes and unforced errors. This structure enables coaches and players to speak a shared language across teams, positions, and schools.
There are currently 70+ tracked criteria. Misuse of these tags or unjustified evaluations
may result in removal from the platform.
We work closely with coaches to expand the criteria list. If you identify an outcome weβve missed, let us know β weβll review and add it if appropriate.
