Let the 1972 Miami Dolphins rejoice. Once again, their perfect season stands alone.

One of today’s biggest NFL rivalries wrote another chapter in their shared storybook set in Orchard Park, New York, as the Buffalo Bills and Kansas City Chiefs met on the gridiron once again.

With perfection on their minds, the Chiefs and their fans (sans Taylor Swift) went into Western New York as underdogs, hoping to take one step closer to an unblemished record.

It wasn’t meant to be. The Bills eeked out some modicum of revenge for their 2023 AFC Divisional round defeat by ruining the Chiefs’ perfect season on a game-sealing interception to win 30-21 in front of the home fans at Highmark Stadium.

Sunday was an afternoon of struggle for Kansas City quarterback Patrick Mahomes – who completed 23-of-33 pᴀsses for 196 yards and three touchdowns. But two costly interceptions spelled doom for his team. He now has a share of the lead for the most picks in the league this season with 11.

His adversary, Buffalo quarterback Josh Allen had a blemish of his own with an interception. But his prowess in the air and on the ground won the day for the Bills as he used his legs to put the game nearly out of reach for Kansas City.

Allen finished completing 27-of-40 pᴀsses for 262 yards, a touchdown, and said interception. He also led the team in rushing with 12 carries for 55 yards and a trip to the end zone as well.

Mahomes committed a foolish error just two plays into the game. He stepped up into the collapsing pocket and, when he felt a Bills pᴀss rusher get a hand on him, let the ball fly.

It sailed over the heads of all his receivers and right into the hands of Bills safety Taylor Rapp for a crucial early interception.

The Bills capitalized on their good fortune with an eight-play drive that ended in paydirt when running back James Cook scampered into the end zone for a 6-0 lead. Kicker Tyler Bᴀss, who has been inconsistent throughout the season, missed the extra point.

Both teams exchanged punts before it was Mahomes & co.’s turn to get on the scoreboard.

The quarterback found rookie target Xavier Worthy for a ten-yard touchdown pᴀss and kicker Spencer Shrader, deputizing for the injured Harrison Butker, knocked through the extra point for a 7-6 lead.

Buffalo responded on the ensuing drive – eating up 4:45 across a nine-play, 70 yard drive that ended with Cook scampering to the end zone again. Bᴀss was able to avenge his miss to take a 13-7 lead.

When the Bills got the ball back, it was Allen’s turn to make an error. Facing a 4th and 3, the Buffalo signal caller floated a half-hearted pᴀss in the direction of тιԍнт end Dawson Knox – only for Kansas City safety Chamarri Conner to jump up and pluck it out of the air.

Like Buffalo on the opening drive, Kansas City made the Bills pay for their carelessness. Mahomes drove down the field – setting up 3rd and Goal before finding a тιԍнт end in the end zone. No, not Travis Kelce – this time it was Noah Gray responsible for the Chiefs regaining the lead with a score of 14-13.

Bᴀss stepped up for Buffalo after his extra point miss, knocking through a 33-yard field goal as the first half came to an end to give the Bills a 16-14 lead as they went to the locker room.

Quarter number three was a snooze fest. The teams put up four consecutive punts – with both teams going three-and-out on their first drives of half number two.

With that slim margin, the Bills could not allow for errors. On a crucial 4th and 2 with 2:17 left in the game, Allen dropped back and looked to his left for a check down pᴀss but waved it off. The pocket collapsed in front of him and he took off.

He kept going. And going. And going. Through sorry attempts at tackling and into the end zone to send Orchard Park into rapture. Bᴀss’s extra point kick made it 30-21.

But that meant Patrick Mahomes had plenty of time to inflict damage. He famously drove the field in 13 seconds to tie the 2021 AFC Divisional round – which the Chiefs would eventually go on to win. Surely, with 2:17 he could orchestrate another comeback.

But the Chiefs began to stall. Mahomes completed an 11-yard pᴀss to running back Samaje Perine just before the two minute warning.

On the opposite side of the stoppage, he found Perine again for a three yard loss. Then, Justin Watson gained ten yards setting up a 4th and 3.

Mahomes thought he gained at least 30 yards with a mᴀssive run, but a holding play erased the gain and made it 4th and 13.

With the game on the line, Mahomes rolled out of the pocket and stared downfield – seeing a wide open Travis Kelce, who up to that point had just two catches for eight yards.

Mahomes uncorked a pᴀss deep. In a feat of amazing athleticism, Bills safety Terrel Bernard jumped up and extended his arms to snag the ball out of the air.

Interception. Ballgame. A perfect season snuffed out.

It’s highly likely these two teams meet again in the playoffs – whatever stage it may be. For Buffalo to overcome its demons, it almost feels destined that they vanquish the Chiefs.

Allen now holds a record of 4-1 over Mahomes in the regular season – a remarkable feat when considering the Chiefs sustained success in the recent years. But in the playoffs? Allen’s 0-3 against Mahomes. Tonight won’t change that.

You know what else doesn’t change? The sound of the corks that have almost ᴀssuredly left many a bottle of champagne in some room in Miami – as the last remaining members of the ’72 Dolphins all celebrate that another year has come and gone with their legacy unblemished as they continue to withstand the test of time.
