Question

Which two teams played in both of the final two AFL Championship games before the start of the Super Bowl era? (That is, Kansas City, won the 1966 AFL Championship, advancing to play against the Packers in Super Bowl I – but looking for the 1964 and 1965 seasons here.)

Answer

Bills and Chargers (and these teams will play again on Sunday). In 1964, the Bills beat the Chargers 20-7 in Buffalo. The same teams met in San Diego the following season, and the Bills won that won 23-0.
