The Kansas City Chiefs were part of the American Football League when they merged with the NFL in 1970. The Pittsburgh Steelers lead the series 23-12 overall and 12-7 in Kansas.
The last time these two teams met was a 2018 contest in Pittsburgh when it was Patrick Mahomes who threw six touchdowns. The Chiefs controlled the game and won 42-37 thwarting a fourth quarter comeback from Ben Roethlisberger.
The Chiefs won the first two meetings at the beginning of the seventies before the Steelers began to dominate the contests.
In 1976 the Steelers were coming off back-to-back Super Bowl wins.
