How the season got here
Where Duke stood among 138 FBS programs by stature after each game (1st is the highest; the CFB Zeitgeist ledger).
Each week as this page showed it at the time. Weeks marked rebuilt came before this page existed: they were built afterward from only what was known by the end of that week.
Our poach model, on his record so far, the win chances for every game he has left, his program, his pay and his background. Ranked against the 132 FBS head coaches this season. The zone words describe the market’s interest; none of them says he is leaving.
What drives his number
The biggest factors in his profile, each against the typical FBS head coach today. The games he has left are priced into the number, not listed here.
▲ Higher
His 3rd season at Duke
▲ Higher
His team is 6-2, outscoring opponents by 17.8 points a game
▲ Higher
Age 52 · neither at his alma mater nor in the state he was born in
How good is this number? It ranks a head coach who leaves for another head-coaching job ahead of one who stays 78 to 82% of the time, and its average came within a point of the share who actually left. What it can’t do
Tested on every FBS head coach from 2012 through 2025, each season scored by a model fit only on the seasons before it. From three games on, given one coach who left for a head-coaching job elsewhere or an NFL coordinator job and one who stayed, it ranked the one who left ahead 79 to 82% of the time; in a season’s first two games, 78%. Its average chance came within a point of the share who actually left. It counts a move a coach makes while he still holds the job; when his school ends it, that doesn’t count, even if another school then hires him.
The live number prices the games he has left with the power model’s ratings from this season. The test priced them with each team’s rating from the season before, because ratings made during past seasons were not kept, so this live version could not be replayed.
Programs new to FBS have no FBS record before this season in the data it reads, so their coaches are scored without one.
It is frozen: it learns nothing from 2026 until a deliberate refit.
A coach hired in December needs his background (age, alma mater, the state he was born in) added before his first game, or he shows as not rated.

ATS is his record against the spread: did his team beat the closing betting line, winning by more than it or losing by less? Lines start in 2013; a dash means fewer than 6 of those games had one. One-score games carry no spread record: a big favorite that wins a close game has almost always failed to cover, so that number would say nothing about the coach.
Passed more than the situation called for under Brewer.
1,780 run and pass snaps at Duke, 2024–2025, his own games, one row per offensive coordinator. Each cell is how much more often he passed than the rest of FBS did in the same situation (field zone, down, distance, score, quarter, same season), in percentage points.

28% of his 133 new players since 2024 came through the portal (FBS programs, same seasons: 29%). His share was 33% in 2024 and 29% in 2026.

Came through the portalNon-portal arrivalsFBS-wide share that season
Each player counts once, in the season he arrived. 2021, the first season of portal tracking here, is left off because its arrival records look incomplete (about 31 new players per FBS team, against 52 in 2022). Portal grade: the site’s position-value-weighted scoring (the same engine as the Portal Heat feed and the “Who won the portal” grade): the value of the players who came in minus the value of the ones who left, ranked against every FBS program’s grade that same season. A season with fewer than 4 transfers in and out is not graded.
“His own” means the player arrived while he was head coach; “inherited” means a predecessor brought him in.

A pick counts toward his tenure when the player’s final college season was one he coached, a checkable rule rather than a claim about who developed the player. A blank note means the player is on a verified roster and arrived on his watch. “Estimated” means no roster record, so the final season is assumed to be the year before the draft.

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.
