As of September 30, 2026, five NFL teams remain undefeated, including the Buffalo Bills, Kansas City Chiefs, Las Vegas Raiders, Minnesota Vikings, and San Francisco 49ers. The Bills and Chiefs are viewed as legitimate contenders based on their recent performances. Buffalo's defense has been strong despite turnover issues, while Kansas City showcased offensive efficiency in their latest win over Miami. The Raiders' unbeaten record is questioned due to their victories over teams with poor records, leading to concerns about their upcoming schedule against tougher opponents. Both the Bills and Chiefs are positioned well as they look ahead to challenging games.
