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.
Miami 2014–2015
Houston 2017–2018
Median of those still in the job, that year of a tenure. A shrinking pool, not a path.
Miami, 2 years
−27.3
68.4 to 41.0 percentile.
Houston, 2 years
−71.5
76.5 to 5.0 percentile.

No prior-season record for the first stop (Miami, 2014) — the data floor starts there.
Houston 2017–2017: ranked 87th the year before he arrived, 77th at its best — went backwards.
Houston 2018–2018: ranked 77th the year before he arrived, 5th at its best — went backwards.
