Which Divisional QB is the Biggest Threat to the Chiefs?

The AFC West division features the Kansas City Chiefs, Los Angeles Chargers, Las Vegas Raiders, and Denver Broncos. The Chiefs have won the division for nine consecutive seasons and aim to secure a tenth straight title in 2025.

Despite the Chiefs' dominance, their rivals have strengthened their rosters for the upcoming season. All three opposing starting quarterbacks share the goal of defeating Kansas City to challenge for the division crown.

Chargers quarterback Justin Herbert enters 2025 with high expectations after a 2024 season where he threw 21 touchdowns with only three interceptions—a career-low interception rate. However, Herbert has historically struggled against the Chiefs, winning just once in eight career matchups against Patrick Mahomes.

The Raiders acquired and extended quarterback Geno Smith, who had a strong 2024 season with the Seahawks. With "nothing to lose and everything to prove," Smith and the Raiders could pose a significant challenge to the Chiefs during their two 2025 matchups—Smith's first games against Kansas City since 2022.

Broncos quarterback Bo Nix, after a promising rookie season, is viewed as potentially leading the biggest threat to the Chiefs. Many consider Denver the Chiefs' primary competition, and if Nix builds on his debut performance, Kansas City will need top-level play to maintain division supremacy.
