I was watching the new Cowboys documentary on Netflix and I was at the part about them facing the Bills in the superbowl which led me to look into how they lost 4 straight and one of the main reasons I saw was that there was a huge talent gap between the AFC and NFC at the time.

From there I looked at other superbowl winners and saw that in the 70s the AFC dominated the superbowls (winning all except the 2 that the cowboys won) and then in the 80s and 90s the NFC dominated winning all except in 84, 98, and 99.

I understand how 1 team can come to dominant the league and form a dynasty but how does it happen that an entire conference can be that much better than the other conference for a decade or longer?
