The Cincinnati Bengals and the Kansas City Chiefs squared off four times within a 13-month span from January 2, 2022 to this past January. The Bengals won the first three, including the 2021 season AFC Championship Game. Kansas City finally got over the hump in a rematch this past season and followed up by winning the Super Bowl.
Many would take that as enough to categorize this as a rivalry, with two (potentially) consistently good teams frequently appearing on one another’s schedules, including in the postseason, participating in competitive contests, the past three games decided by three points.
