Coordinator years

Defensive coordinator across 4 programs, 4 stints, before and after wearing the head-coach hat — every season measured on the same axis, whether he personally ran the unit or someone else did.

How to read this. Coordinator seasons come from our coordinator career records; head-coaching-era seasons are the same unit's FBS-relative percentile for those years, regardless of who coached it, read directly from the staff assignments record. A role change (a “hinge”) is a fact, never a performance verdict — only the season-by-season data itself is colored by outcome.
