In a never-say-die showdown between two of the NFL's top teams, and two of its bright young quarterbacks, the Bills and Chiefs played a classic Sunday night decided by one of them calling tails and the other making him pay for it.
Josh Allen's decision on the overtime coin toss was his only mistake for Buffalo all night.
Patrick Mahomes promptly followed it by marching Kansas City downfield against the NFL's top-ranked but exhausted defense, then finding Travis Kelce in the corner of the end zone from 8 yards, giving the Chiefs a memorable 42-36 victory.
Kansas City earned a spot in their its consecutive AFC championship game.
"The guys didn't flinch," said Chiefs coach Andy Reid, whose team will play the Cincinnati Bengals next Sunday for a spot in the Super Bowl that would be Kansas City's third straight. "You talk about an epic game, well, that's the way the players took it. They had tremendous respect for Buffalo and they knew it was going to be a battle and they kept going."
What was Reid's advice for Mahomes down the stretch?
"When it's grim, be the grim reaper, and go get it," Reid said. "He made everyone around him better."
Indeed, the lead changed hands three times in the final two minutes of regulation before Harrison Butker, who earlier had missed a field goal and extra point, drilled a 49-yarder for Kansas City as time expired to force overtime.
The Chiefs won the coin toss and Mahomes took care of the rest.
"I'll remember this for the rest of my life," Mahomes said.
He finished with 378 yards passing and three touchdowns, including a 64-yarder to Tyreek Hill during the thrilling final minutes of regulation and the clutch throw to Kelce that sent players streaming off the bench.
"We got tremendous leaders on both sides of the ball, whether it's offense, defense or special teams," Hill said. "Nobody panicked. Nobody was like, 'Oh, the game is over, there's 13 seconds left.' We just made plays."
Allen did everything he could to prevent another season-ending loss in Arrowhead Stadium. He threw a go-ahead touchdown pass to Gabriel Davis with 1:54 left in the regulation, then another to Davis - his playoff-record fourth TD catch of the game - with 13 seconds remaining in regulation.
Allen's only mistake? His coin toss call.
He finished with 329 yards passing, and Davis with eight catches for 201 yards, as the Bills - who had beaten the Chiefs in October - lost their ninth straight road playoff game dating to their last victory in the 1992 season's AFC championship.
"They made a couple more plays than we did obviously down the stretch," Bills coach Sean McDermott said. "The guys played their guts out, and you got to do a little better on the last couple of plays there."
In a playoff game for the history books Sunday night, the Bills and Chiefs played 58 minutes that few will remember. And about two minutes and an overtime that few will forget.
The Chiefs were leading 26-21 when Allen, who had been nearly perfect all night, connected with Davis for the third time in the game — a fourth-and-13 dart that gave the Bills the lead.
Not to be outdone, the Chiefs answered when Mahomes found Hill over the middle. The fleet-footed wide receiver ran away from cornerback Levi Wallace for a 64-yard touchdown that gave Kansas City the lead back.
Then it was the Bills' turn. Allen threw a 28-yard pass to Davis, hit him again for 12 yards, then found Emmanuel Sanders to give coach Sean McDermott's team a chance with 17 seconds on the clock.
Allen hit Davis right between the numbers, their 19-yard strike giving him the postseason-record, but not the victory.
Mahomes wasn't done conjuring up playoff magic. He found Hill for 19 yards, then hit Kelce for 25 more. That gave Butker a chance to try a 49-yarder into a slight, chilly breeze as time expired.
Naturally, it split the uprights.
A fitting way to end a divisional-round weekend filled with last-second heroics.
