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.
Liberty 2021–2022
East Carolina 2025–2025
South Florida 2026–2026
Median of those still in the job, that year of a tenure. A shrinking pool, not a path.
