The tenure clock
Every stop re-aligned to its own first year, so the stops stack instead of scrolling past each other. The gray dashed line is a reference, not a path: each point is the median of whoever was still in the job that year, across every real OC/DC stint since 2014 at that role, and the pool shrinks year over year because surviving to a later year means not having been fired.
Illinois 2023–2025
Notre Dame 2026–2026

Illinois 2023–2025: ranked 98th the year before he arrived, 44th at its best — went backwards.
Notre Dame: just hired, no season coached yet.
