Kickoff precipitation probability unresolved from admissible same-day data; WVI ultimately held at 0 through F-76/P1 because the market had already moved one full point toward the weather.

RCF: FALSE — zero offensive-line starters are unconfirmed. Kansas City LT Josh Simmons is confirmed OUT with Kahlil Benson projected to start. Model σ: Margin 13.5 / Total 13.5 Market Anchor: Kansas City -6.5 | Total 46.5 | Indianapolis ML fair probability 29.361%

STARTING QB COMPOSITE SCORE:

Indianapolis — Daniel Jones — Projected Passing Yards: 215.5 | Projected INT: N/A | Projected TD: N/A | 2025 net YPA: 7.249 over 406 dropbacks = TQBS N/A

Kansas City — Patrick Mahomes — Projected Passing Yards: 270.8 | Projected INT: N/A | Projected TD: N/A | 2025 net YPA: 6.332 over 536 dropbacks = TQBS N/A

WEATHER:

Arrowhead Stadium is outdoors.

• Wind: 4–7 mph at kickoff → no WVI adjustment
• Temperature: ~70°F → no WVI adjustment
• Kickoff precipitation probability: Unresolved
• Earlier game-window forecasts: 59%–72% rain/showers
• Same-day KCTV5 update: rain tapering to 30% by 9:00 AM, but no valid kickoff-hour precipitation probability was supplied

The total opened 47.5 and fell to 46.5, with 77% of reported total handle on the Under, and a sourced report attributed the move to the rain forecast.

WVI = 0.00 through F-76/P1.

Even if the ≥60% precipitation clause had produced a -0.75 adjustment, the model would decline it because the market had already moved a full point in the same direction.

TEAM PLAYING AT HOME:

Kansas City Chiefs — Yes

Home field is already embedded in the Kansas City -6.5 market anchor. No additional standalone +4% modification is applied because that would double-count market information.

PUBLIC FAVORITES DELTA:

Kansas City has approximately 69%–80% of spread tickets, depending on source, and OddsShopper reported 80% of spread handle.

Kansas City does not meet the model’s 90%+ money threshold.

No Public Favorites Delta applied.

GAME PREDICTIONS

1. Team to Win: Kansas City Chiefs

• True Score Simulation: Kansas City 68.53%
• Indianapolis: 31.47%
• Market vig-free Kansas City probability: 70.64%
• Kansas City remains the model favorite because μ_margin is anchored to Kansas City -6.5.
• CF: 68.53%

MSI: Not triggered.

Indianapolis model win probability: 31.471% Indianapolis vig-free market probability: 29.361% Raw ML edge: +2.110%

The required dog-moneyline edge is at least 6%, so MSI does not trigger.

2. Final Score Prediction:

Kansas City Chiefs 27, Indianapolis Colts 20

• Simulation means: Kansas City 26.52, Indianapolis 20.09
• Model total: 46.61
• Model margin: Kansas City +6.43
• Market anchor: Kansas City -6.5 / Total 46.5

2a. Moneyline Surprise:

No Moneyline Surprise projected — model and market align.

Indianapolis shows a nominal +2.11% ML discrepancy, but that is below the minimum tier and is attributable to the market’s own ML-versus-spread pricing divergence rather than an independent model disagreement.

2b. True Score Simulation (TSS):

• Simulated Win Probability — 100,000 Games:
• Kansas City: 68.53%
• Indianapolis: 31.47%
• Simulated Average Score:
• Kansas City: 26.52
• Indianapolis: 20.09
• Most Common Sim Occurrences:
• Kansas City 24-20 Indianapolis — 0.21%
• Kansas City 26-19 Indianapolis — 0.20%
• Kansas City 28-18 Indianapolis — 0.19%
• Kansas City 24-22 Indianapolis — 0.19%
• Kansas City 24-19 Indianapolis — 0.19%
• P(|margin| ≥14): 36.92%
• Script Note: FIRES
• Zero-floor clamp effect on Indianapolis ML: approximately +0.001 percentage point — inert

3. First Team to Score: Kansas City Chiefs

• Model-based first-score probability: 57.41%
• Market-based first-score probability: 58.26%
• No first-score market price was captured, so this market is not graded.
• CF: 57.41%

4. Total Points: 46.5 — Over/Under

• Over 46.5: 50.11%
• Under 46.5: 49.89%
• Market fair bar: 50.00%
• Over edge: +0.11%
• Because μ_total equals the 46.5 market anchor and no ledger adjustment survives, the total is definitional under C-12.
• Prediction: No qualifying total edge
• CF: N/A — no qualifying edge

Alt Total Model

• Over 37.5 — 74.96%
• Over 44.5 — 56.00%
• Over 46.5 — 50.11%
• Over 48.5 — 44.20%
• Over 55.5 — 25.28%

5. Point Spread: Kansas City -6.5

• Kansas City -6.5 cover: 49.88%
• Indianapolis +6.5 cover: 50.12%
• Market fair bar: 50.00%
• Indianapolis edge: +0.12%
• Because μ_margin equals the posted spread, the ATS result is definitional under C-10.
• Prediction: No qualifying spread edge
• CF: N/A — no qualifying edge

Alt Spread Model

• Kansas City by 1+ — 67.17%
• Kansas City by 3+ — 61.69%
• Kansas City by 6+ — 52.87%
• Kansas City by 7+ — 49.88%
• Kansas City by 10+ — 41.04%
• Kansas City by 14+ — 30.03%
• Kansas City by 17+ — 22.77%
• Kansas City by 21+ — 14.81%

6. FIRST TOUCHDOWN:

Indianapolis:

• Jonathan Taylor — First-TD price: N/A
• Josh Downs — N/A
• Tyler Warren — N/A
• Keenan Allen — N/A
• Alec Pierce — N/A
• Daniel Jones — N/A

Kansas City:

• Kenneth Walker — First-TD price: N/A
• Rashee Rice — N/A
• Xavier Worthy — N/A
• Travis Kelce — N/A
• Patrick Mahomes — N/A

First-TD names were captured, but first-TD prices were not, so no first-TD market can be graded.

7. ANYTIME TD MODEL:

Indianapolis Colts:

• Jonathan Taylor — 39.82%
• Josh Downs — 32.90%
• Tyler Warren — 31.55%
• Keenan Allen — 23.90%
• Alec Pierce — 17.50%
• Daniel Jones — 11.51%
• Laquon Treadwell — 5.55%
• Mo Alie-Cox — 4.15%
• Seth McGowan — 3.52%

Kansas City Chiefs:

• Kenneth Walker — 43.60%
• Rashee Rice — 42.26%
• Xavier Worthy — 37.07%
• Travis Kelce — 34.76%
• Tyquan Thornton — 27.91%
• Patrick Mahomes — 16.51%
• Noah Gray — 12.39%

ATD grading status: UNGRADED.

The snap-based λ allocation fails an internal coherence test:

• Laquon Treadwell receives a 5.55% TD probability despite zero projected touches
• Emmett Johnson projects for 5.38 touches but receives no λ because no published snap share was available

Because the touchdown allocation set and projected-volume set do not match, no ATD betting verdict is accepted, including Xavier Worthy’s nominal +7.31% edge.

Official model verdict: NO QUALIFYING EDGE — NO BET

INSIGHTS

• Kansas City strengths: Mahomes-led passing budget of approximately 271 yards; 65.5 projected offensive plays; strong target concentrations for Kelce and Worthy; market and model both make Kansas City a clear favorite.

• Kansas City weaknesses: LT Josh Simmons is OUT, requiring Kahlil Benson to start; the 2025 pass-protection baseline does not reflect that change; Week 1’s low pass rate was heavily influenced by a 31-10 positive game script.

• Indianapolis strengths: Jonathan Taylor projects near 100 rushing yards; Daniel Jones’ adopted 2025 net YPA is stronger than Mahomes’ 2025 rate; Indianapolis shows a small positive raw ML discrepancy.

• Indianapolis weaknesses: Only 50.0 projected offensive plays; model moneyline probability remains only 31.47%; the raw dog edge is 0.89 percentage point below the minimum Lean threshold.

• Winning edge: Kansas City carries the stronger baseline scoring profile and approximately 6.5-point implied margin, but the model contains no independent ledger adjustment large enough to move away from the market.

SPORTSBOOK LIABILITIES:

• Kansas City side: Public interest is heavily concentrated on Kansas City, with approximately 69%–80% of tickets and one source reporting 80% of handle.

• Total: 65% of tickets are on the Over but only 23% of money is on the Over, meaning approximately 77% of money is on the Under.

• Line movement: Total moved 47.5 → 46.5, aligning with Under money and the rain narrative.

• Indianapolis ML: The market’s heavy-favorite moneyline pricing implies a wider effective spread than the posted -6.5, creating the nominal dog ML discrepancy.

99.99% PARLAY:

N/A — no graded leg clears the model’s qualifying edge threshold.

A high-confidence five-leg parlay is not constructed by artificially inflating confidence levels.

The largest graded edge is only +2.110%, and the strongest nominal prop/ATD discrepancies are blocked or ungraded by model-integrity rules.
