Chiefs vs. Seahawks odds: Chiefs open as 1.5-point underdogs against defending champs

The Kansas City Chiefs have opened as 1.5-point underdogs against the defending champion Seattle Seahawks ahead of their Week 7 matchup on Sunday Night Football, according to FanDuel Sportsbook. This marks the first time this season that the undefeated 5-0 Chiefs have not opened as betting favorites. The game features the return of running back Kenneth Walker to Seattle, where he won Super Bowl LX before joining Kansas City.

Seattle enters the contest at 3-3 following back-to-back defeats, including a Thursday night loss to the Denver Broncos that gives them extra rest. Kansas City remains the AFC's only undefeated squad after securing a 22-6 victory over the Los Angeles Chargers following their bye. Walker currently leads the NFL with 665 rushing yards through five games.
