Tim inherited the Arizona Cardinals DB room from Cedric Mack (1983β1990), and handed it to Aeneas Williams (1991β2000).
The room is reconstructed from arrival order among durable members (β₯4 seasons with the club) at the playerβs position group β a lineage by arrival, not a week-by-week depth chart. Distinct from the league-wide positional GOAT torch.
