The Kansas City Chiefs ran their streak of AFC West championships to five in defeating the Miami Dolphins 33-27 on Sunday.
The Chiefs last week clinched a playoff berth by beating the Denver Broncos. Their next regular-season goal is to secure the AFC's No. 1 playoff seed and the first-round postseason bye.
The 12-1 Chiefs are batting the 11-1 Pittsburgh Steelers for the AFC's top seed.
The Chiefs, who began in 1960 as the AFL's Dallas Texans, had never won back-to-back division championships until the current streak, which began in 2016.
