Every single year we get a new Super Bowl to add to this list. But every single year, it seems, we get a new Super Bowl to add to the top of this list. Such is the nature of the modern NFL championship game: the league's on-field and roster-construction rules and have resulted in close games and increasing parity.

The Chiefs have won the Super Bowl the past two years in a row and have made the championship five times in the last seven seasons. If they win again this year, they’ll become the first team in NFL history to win three Super Bowls in a row.

The Chiefs, despite their dynastic dominance in reaching a fifth Super Bowl in the past six seasons, did not go undefeated this season en route to Sunday’s Super Bowl LIX against the Eagles. They lost one regular-season game, and it came after a 9-0 start.
