No NFL team has ever won three consecutive Super Bowls. The Chiefs will have an opportunity to do exactly that when they face the Eagles in two weeks.

Sunday’s win over the Bills wasn’t an easy one, but the Chiefs did avenge their only meaningful regular-season loss. They did so by making key plays at critical times on both sides of the ball.

This is essentially how Kansas City has operated all year. For this team, winning close games has become routine—it has now won 17 straight one-score games.

Defensive coordinator Steve Spagnuolo’s unit did have some trouble corralling Josh Allen and the Bills, who tallied 374 yards and 29 points. However, a pair of 4th-down stops in the fourth quarter gave the Chiefs a chance to end the game with the ball in their hands.

Kansas City did exactly that, with running backs Isiah Pacheco and Samaje Perine each picking up first-down receptions to close out the game.

It was a fitting way for Kansas City’s offense to end the game. Quarterback Patrick Mahomes regularly turned to his secondary targets a week after leaning heavily on star tight end Travis Kelce.

Kelce had seven catches for 117 yards and a touchdown against the Houston Texans in the divisional round. Buffalo did a great job of limiting him to two catches and 19 yards, but that opened the door for Xavier Worthy (6 catches, 85 yards, 1 TD) and JuJu Smith-Schuster (2 catches 60 yards) to make big plays in the passing game.

Of course, it helps to have Mahomes, who remains the biggest reason why a Super Bowl trifecta is even possible. He was mostly efficient through the air and lethal with his legs on Sunday, finishing with 245 passing yards, 43 rushing yards and three combined touchdowns.

Yet, the Chiefs’ effort to build a dynamic offense that complements their fourth-ranked scoring defense—and do so throughout the season—is impressive. Worthy is a rookie, while Smith-Schuster, Kareem Hunt and DeAndre Hopkins were all added after the end of the preseason.

After two consecutive Super Bowl wins, the Chiefs could have become complacent. Instead, they’ve adapted, evolved and set themselves up for a shot at history.
