Written before the game and kept as published. Final: Indianapolis Colts 30, Kansas City Chiefs 33 (OT) — the graded call is above.
The Colts travel to face the Chiefs in Week 2. Our power ratings put the Chiefs 16th of 32 at +0.4 (Average tier) and the Colts 24th at -1.6 (Average tier) — a 2.0-point gap that home field widens to a 2.5-point line on the Chiefs, 57% to win. It rates as the 7th-widest of the 16 games in Week 2.
The sharpest unit gap in the game runs one way: the Chiefs offense grades +1.3 (12th of 32) against a Colts defense at -1.8 (22nd) — 3.0 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Colts offense (-0.6, 21st) meets the Chiefs defense (-1.0, 16th), a 0.5-point gap. Special teams adds to it: the Colts grade +0.7, 4th in the league, against +0.2 (22nd) on the other side — close to a point of hidden margin.
Zoom out to the full season and the model projects the Chiefs at 10.6 wins (favored in 10 of 17) and the Colts at 6.7 (favored in 7) — 3.9 wins apart across the year. By win probability this is the 13th-hardest game on the Chiefs' schedule and the 4th-hardest on the Colts'.
Recent history, for context only: 10 regular-season meetings since 2002, 6-4 in the Colts' favour, plus 5 playoff games. They last met in 2025: Chiefs won 23-20 in November. Over their last 4 meetings the Chiefs are 2-2. It is not an input to the line — rosters turn over faster than series records do.
Calibration check, because a near-even number is the easiest kind to overtrust: across 3266 walk-forward games (2013-2024) the model gave a side 55-60% in 797 of them, and those sides won 57%. The Chiefs at 57% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
