The National Football League (NFL) champion Green Bay Packers defeated the American Football League (AFL) champion Kansas City Chiefs by the score of 35--10 . </P> <P> Coming into this game, considerable animosity existed between the AFL and NFL, thus the teams representing the two rival leagues (Kansas City and Green Bay, respectively) felt pressure to win . The Chiefs posted an 11--2--1 record during the 1966 AFL season, and defeated the Buffalo Bills 31--7, in the AFL Championship Game . The Packers finished the 1966 NFL season at 12--2, and defeated the Dallas Cowboys 34--27 in the NFL Championship Game . Still, many sports writers and fans believed any team in the older NFL was vastly superior to any club in the upstart AFL, and so expected Green Bay would blow out Kansas City . </P>
