College stats are not imported for this profile yet.
StatVault has the verified college attribution (Illinois; Joliet Junior College), 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.
Cap inherited the Chicago Bears TE room from Tim Wrightman (1985–1986), and handed it to Jim Thornton (1988–1991).
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.
Statistical + physical similarity across every player in the database, position-relevant (0–100%).
