Where this defender ranks vs the field
Box-score production percentiles vs the position cohort
Concern: passes defended (18th 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.

What the box score actually says
29 tackles. 0 passes defended. 0 interceptions. 5 TFL.
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.
