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 2019–2021
SMU 2022–2025
