Falcons 62 – Saints 7 (1973)
Archie Manning is a football legend but nobody would know if they only saw this game. The quarterback had a nightmare against the Falcons as the Saints came up short in every department. He threw five interceptions on a day where nothing went right for him. Atlanta even returned a 65-yard pick-six in one of the biggest beatdowns of the decade.
Many people think that this is one of the NFL’s best rivalries but it was one-sided in their early days. The 55-point win margin remains the biggest between these two great franchises. Soon New Orleans found their feet and improved but this was a symptom of their early struggles (via Clarion Herald).
