Where this defender ranks vs the field
Box-score production percentiles vs the position cohort
Concern: tackles (0th percentile).
Box-score production (6)
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.
