their huge 2019 campaign, the Chiefs were ready to build up. However, running back Damien Williams opted out of playing the 2020 season due to the COVID-19 pandemic. This did not matter much, however, as the Chiefs used their first-round draft pick on star LSU running back Clyde Edwards-Helaire. 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 overcame 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. Super Bowl LV against the Tampa Bay Buccaneers was the fifth meeting between Mahomes and Tom Brady. The series was 2-2 heading into the game. What was supposed to be a battle for the ages instead became a domination. The Chiefs could not get anything going right, not scoring a single touchdown in the game for the first time in Mahomes' career, as the Buccaneers crushed them 31–9. With the loss, the Chiefs were denied a second straight NFL title, which would have ended the streak at 15 for consecutive years without repeat
