text: 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 world champions.
