In a thrilling Week 7 matchup, the Kansas City Chiefs defeated the San Francisco 49ers 28-18, marking their Super Bowl rematch. This victory keeps the Chiefs as the only unbeaten team in the NFL this season. Despite a lackluster performance from quarterback Patrick Mahomes, who registered the lowest passer rating of his career, the Chiefs displayed resilience through their dominant defense and special teams. The 49ers struggled with turnovers and inconsistent play, leading to another disappointing loss against the Chiefs, raising questions about their performance moving forward. Notably, Saquon Barkley shone in a different game against the Giants, while the matchup between Mahomes and 49ers quarterback Brock Purdy underlined the challenges each faced in delivering a winning performance.
