This matchup features two storied franchises with ties to the early days of the American Football League (AFL). Buffalo was one of the inaugural members of the AFL in 1960, as were the Dallas Texans, who relocated to Kansas City and became the Chiefs after winning the 1962 AFL title.

The Buffalo Bills just handed Patrick Mahomes and the Kansas City Chiefs their first loss in four games. The Chiefs entered Sunday’s high-profile matchup on a high after winning three in a row, but they finally found their match in Josh Allen and Co.
