text: The 2020 season was a dominant season for the Chiefs, as they managed to enjoy their fourth straight 4–0 start, an NFL record. They also managed to break the franchise record for longest winning streak in history (previously held by the 2015 Chiefs) at 12 after a 34–20 week 3 win at Baltimore. Their first loss came at the hands of the Las Vegas Raiders, who beat them in Kansas City for the first time since the Chiefs' miserable 2012 season; the loss ended the Chiefs' franchise-record winning streak at 13. The Chiefs then went on to win ten straight games on their way to a league-high and franchise-best 14–2 record.
  In the postseason, the Chiefs started off against the Cleveland Browns, who had just acquired their first playoff win in a quarter-century. The Chiefs held on to a 19–3 lead before Patrick Mahomes went down with a minor concussion. After that, the Browns attempted a comeback, trailing 22–17 in the final minutes. That's when Chiefs backup quarterback Chad Henne hit Tyreek Hill perfectly on fourth and inches in one of the gutsiest play calls in NFL history, to seal the victory. In their third straight AFC Championship Game at home (an NFL record), the Chiefs played the Buffalo Bills, who, like the Browns, had also just overcome a quarter-century playoff win drought. Despite trailing 9–0 in the first quarter, the Chiefs would remind fans of 2019 by scoring three straight touchdowns on their way to a thrilling 38–24 victory, to win their second straight Lamar Hunt trophy.
