The Bills' magical 2020 season came to a crashing end in the AFC Championship game, losing to the Chiefs 38-24.
Since that night in Kansas City, so much focus has been on what has to be done to beat that team when they meet in that moment again.
And while 12 months have passed since that defeat, it's far from forgotten as the Bills and Chiefs are set to square-off in the playoffs again this Sunday night.
"We don't want to have that feeling that we had there last year," Bills quarterback Josh Allen said. "We know our season ended there last year and now we have to do everything in our power to put our foot forward and make sure it doesn't end there this year."
"I think a lot of guys had that loss in their mind all offseason," Bills safety Jordan Poyer said. "Really kind of fired them up throughout the offseason. Kept that energy going into the season and obviously remember what happened last postseason. Nobody wants to go home yet. Great opportunity against that same opponent."
"Things like that you don't forget," Bills running back Devin Singletary added. "How we lost. When we lost. Of course we still have that bad taste in our mouth. But coming up this week we get a chance to redeem ourselves and get that bad taste out of our mouths. Things like that, it's always going to motivate you. I don't care what you say, it's always going to motivate you. So we're ready to go. We're looking forward to Sunday."
The lasting image from that game is Stefon Diggs standing alone as the last Bills player on the field after the game, watching the Chiefs celebrate as confetti whipped through the air.
Diggs has already explained why he did that, wanting to soak in and remember the pain to help as motivation moving forward.
But now as the postseason rematch awaits, that moment not burning as hot for the Bills wide receiver.
Part of that is because these two teams already faced off back at Arrowhead earlier this season, with the Bills winning 38-20 in October.
Similar to the Patriots, there was the thought walking off victorious that another meeting would come down the line.
"I had a feeling if we wanted to get to the Super Bowl we were going to have to beat them," Poyer said. "Here we are some x-amount of weeks later in that position for a great opportunity to go play our best football."
"Everybody knew that," Diggs said. "The Chiefs are a hell of a team. They got all the talent in the world. They've been playing at a high level. They've been to the Super Bowl twice. They've got a hell of a quarterback. Hell of receivers. Good defense. They're a good team. Something that we can look forward to as far as the challenge and put ourselves in the position to have success."
Success this time around against the Chiefs will put the Bills back in the AFC Championship game for a 2nd-straight season.
