The biggest comeback in Super Bowl history is, of course, the Patriots' historic comeback after trailing 28-3 to the Atlanta Falcons in Super Bowl LI.'
The Patriots trailed 28-3 late in the third quarter before successfully mounting five unanswered scoring drives throughout the final 20 minutes of regulation and overtime. They eventually won, 34-28.
The last 20 years of Super Bowls have left us with many of the biggest comebacks in Super Bowl history, perhaps because 21st-century offenses are more capable of erasing large deficits.
The Chiefs are one such example. In Super Bowl LIV, Kansas City trailed San Francisco, 20-10, with only half the fourth quarter remaining. But Patrick Mahomes and the Chiefs' offense found the end zone three times in the final seven minutes, ultimately winning 31-20.
