Denver remains a narrow 23-20, 55% uncalibrated lean, based on offensive-line continuity and its defensive baseline, not an unchanged copy of the 2025 pass rush. Jonathon Cooper's exempt-list absence was a missed pre-existing input and is now explicitly included. Kansas City has ruled out left tackle Josh Simmons and safety Chamarri Conner. Mahomes has no final game designation, but recovered game effectiveness is unproven. These competing risks do not support moving a near-toss-up estimate by another five points. The house targets and player percentages are unchanged. Operator articles favor Kansas City, a counterargument rather than an executable price edge.
Winner reasoning, risks and sources
UNCALIBRATED subjective research estimate (55%); small original lean with unusually important quarterback and line gates.
- Cooper is unavailable on the exempt list, weakening the personnel continuity behind Denver's historical sack total.
- Mahomes has no game designation; no final inactive list is verified and post-surgery game effectiveness is unknown.
- Simmons is out. Benson is a likely replacement, not a confirmed starting lineup. Jones' Saturday absence was precautionary but workload and effectiveness remain uncertain.
- Kansas City's run game, home field and defensive pressure provide a credible winning path; Nix is also returning from a postseason injury.
- NWS city-point winds near kickoff are a proxy only. Exact stadium weather and final inactives remain unresolved. No comparable market movement or executable price was verified.
