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.
SMU 2014–2014
Hawai'i 2015–2015
UTEP 2016–2017
Median of those still in the job, that year of a tenure. A shrinking pool, not a path.

No prior-season record for the first stop (SMU, 2014) — the data floor starts there.
Hawai'i 2015–2015: ranked 25th the year before he arrived, 23rd at its best — went backwards.
UTEP 2016–2017: ranked 64th the year before he arrived, 27th at its best — went backwards.
