ESPN News: On Sunday, the Kansas City Chiefs and Buffalo Bills reignite the AFC’s top playoff rivalry.

Kansas City-Buffalo, the movable feast of NFL playoff rivalries, will take center stage again Sunday.

The Chiefs and Bills will play in the postseason for the fourth time in five seasons in the AFC championship in Kansas City. No other teams have met as often this decade. None has been as frustrated as the Bills.

The teams have split their eight games in the 2020s, with one defining difference — the Bills have won the last four in the regular-season and the Chiefs have won all three in the playoffs.

The two-time defending Super Bowl champion Chiefs’ chance for an historic Super Bowl three-peat hinges on a playoff four-peat over the Bills as they look to avenge a regular-season loss.

Since perennial MVP contenders Patrick Mahomes and Josh Allen first met in 2020, the match has featured multi-tasking quarterbacks, head coaches who have risen to the head of their class, and fan bases that consider freezing temperatures just another excuse to go shirtless.

“You always remember the feeling of not pulling through,” Buffalo quarterback Allen said this week. “It sticks with you for awhile. It really doesn’t leave. We’re grateful to have another opportunity at it. It’s another week we get to play.”
