The numbers, worn by the Chiefs

The Chiefs went 5-2, but a record is a result, not an explanation. The explanation starts with EPA/play: Buffalo-style, every snap either moved the expected score or it didn’t. The Chiefs offense averaged +0.113 — 7th of 32, meaning a typical snap gained about 0.11 points of expected score. Their defense allowed -0.023 per play (12th — remember, lower is better on defense).

Success rate tells you the texture: 47.1% of snaps kept them on schedule against a league average near 44%. Pair that with pace and you get identity: at 29.8 seconds a snap they ran the 21st-fastest offense of 32 — middle of the league in tempo.

Raw EPA flatters teams with soft schedules, so the net rating re-solves it against opponents: +0.117est.. Multiply by the fitted 15.1 points per unit and the Chiefs are worth about +1.8 points against a league-average team on a neutral field — that number, plus era-fitted home field and the QB adjustment, is the whole model margin on every game card.

Playoff odds come from 10,000 simulated seasons — full scores, because tiebreakers need points. The Chiefs made the field in 82% of them, won the division in 47%.

Settle every game against its closing spread and you get the ATS record: 3-4, beating their number by +1.4 points per game on average. As favorites they went 3-2; as dogs 0-2. Their games went 3-4 to the over. Descriptive, not predictive — 52.38% is break-even at standard vig, and last season’s cover rate does not persist.

A concrete game: Chiefs at Seahawks, week 7, closed at SEA -3. That line sits on a key number, so the model prices a 7.5%est. push — and ½-point at risk of 7.5%, which is why buying the half point matters here and not at 5½.

Where the model margin and the market disagree, remember the disagreement entry: model-preferred sides have gone 49.93% ATS. The market is the sharper instrument; the model is the explainer.
