1966 Kansas City Chiefs season

With an 11–2–1 regular season record, the Chiefs won the Western Division and defeated the Buffalo Bills 31–7 to win their second AFL Championship, their first in Kansas City.

By winning the AFL Championship, the Chiefs were invited to play in the inaugural AFL-NFL World Championship Game, which would later be known as Super Bowl I, against the NFL's Green Bay Packers. The contest between the best of the NFL vs AFL was a contest for one half, but the Packers pulled away in the second half for a 35–10 victory.

The host Bills entered the AFL title game as two-time defending champions, but the visiting Chiefs were three-point favorites, mainly because of their explosive and innovative offense led by head coach Hank Stram. The Bills were a more conventional team with a solid defensive line and a running mindset on offense. The two teams had split their season series, played early in the schedule without weather as a factor, with the road team winning each.

Played in a chilly drizzle, a Bills fumble on the opening kickoff gave the Chiefs a short field to work with. Quarterback Len Dawson immediately took advantage of it, hitting Fred Arbanas for the game's first score. Buffalo quarterback Jack Kemp's first pass for the Bills was a 69-yard score to Elbert Dubenion. Late in the second quarter and trailing 14–7, Kemp led the Bills to the Kansas City 10. Bobby Crockett was open in the end zone, but Kemp's pass was intercepted by Johnny Robinson, who returned it 72 yards. That set up a Mike Mercer field goal to close out the first half with a ten-point lead.

Buffalo found no offensive rhythm in the second half, and the third quarter was scoreless. The Chiefs closed the game out in the fourth quarter with Dawson found Chris Burford for a 45-yard gain, setting up a one-foot touchdown run by rookie running back Mike Garrett, extending the lead to 24–7. Garrett scored his second touchdown less than two minutes later, following another Bills fumble.
