Bobby Hebert had a career 12-0 record against AFC Teams by 1991 as a Saint Quarterback

The NFC dominated the AFC back then - much in the way you see the shift to AFC dominance now with the Chiefs.

The Niners forced everyone in the NFC in the 80s and early 90s to adapt or die. That effort to capture or at best keep pace with the Niners led to defensively dominant teams like the Giants, the Bears, the Cowboys, the Skins and the Saints.

The AFC was seen as finesse and were typically dispatched by the more physical NFC teams.
