I would wonder if having the same damn teams on top all the time, especially in the AFC has been significant. I'm good with it, since it includes the Pats, but if you aren't the Pats/Donx/Steelers/Ravens/Colts, then you haven't been to a SB in at least 10 years, and probably not even an AFC championship game.
But I find that hard to believe as a factor. We had the same damn thing in the NFC for like 15 years too. SF/Dal/NYG/Wash/Chi from 1981 to 1995.
