ORCHARD PARK, N.Y. -- As the confetti fell at Arrowhead Stadium, Stefon Diggs stood, hands on his hips, and watched the Kansas City Chiefs celebrate reaching a second consecutive Super Bowl.
The Buffalo Bills receiver taking in the moment after the 2021 AFC Championship Game is one of many lasting images from the hard-fought games between the Chiefs and the Bills over the past few years.
While the Chiefs have been to three Super Bowls since the 2019 season, winning two, the Bills haven't gotten beyond the AFC title game and have been knocked out of the postseason twice by the Chiefs.
