Where this defender ranks vs the field
Box-score production percentiles vs the position cohort
Elite: tackles for loss (84th percentile). Concern: qb hurries (24th percentile).
Percentiles are versus same-position peers with enough snaps this season, based on box-score production. There are no play-by-play efficiency bars here: CFBD's play-value model credits offensive players only, so no defensive EPA exists to rank.

Counts only, never a rate — splash-event sample sizes this small (interceptions, pass breakups, TFL) are noise as a rate and signal only as a tally.
