‘The Buffalo All-Americans won the NFL championship in 1921 – or so they thought. Halas, player-coach of the Chicago Staleys, challenged the All-Americans to an exhibition game after the season was over. Buffalo had already won, 7-6, in Chicago on Thanksgiving Day, but the Staleys won the exhibition, 10-7. Then Halas convinced other owners to crown his team as champs by arguing that the game that should not have counted actually counted for more, as a tiebreaker.’
