StatVault aggregates multiple open-licensed and proprietary sources into a single profile. The depth indicator above shows which layers are available for this player.
Pre-1999 players have bio + draft data but counting stats are not available from any freely-licensed source. Players with ★ Career Only see verified career aggregates from nflverse draft_picks.
Production per snap — the box score normalized by opportunity. SIS is z-scored within linebackers, shrinkage-regularized so small samples don't spike, over the NFL snap-count era (2012+).
Amber = this player (normalized to own peak). Indigo = average linebackers aging curve. Group peak age: 32. Source: StatVault KV-H era (1999+).
Percentiles compare each raw measurement against position peers, the full combine pool, and the same draft class where enough samples exist.

College stats are not imported for this profile yet.
StatVault has the verified college attribution (Michigan), but no parsed college box-score table is present in this profile artifact. The section stays here so every profile has a consistent college-stats landing point without fabricating unavailable rows.
Career teammates and draft class, derived from year-by-year rosters — every name is linked.
Frank inherited the Seattle Seahawks LB room from Benson Mayowa (2013–2021), and handed it to Jamal Adams (2020–2023).
Frank inherited the Kansas City Chiefs LB room from Ben Niemann (2018–2021), and handed it to Willie Gay Jr. (2020–2023).
The room is reconstructed from arrival order among durable members (≥4 seasons with the club) at the player’s position group — a lineage by arrival, not a week-by-week depth chart. Distinct from the league-wide positional GOAT torch.
