The AFC does suck compared to the NFC. It's just that the top 2-3 teams in the AFC are better than the top 5-6 teams in the NFC.
That explains the whopping 33-32 advantage that the NFC had vs the AFC this year, only the 7th time the NFC has won out of the last 20 years and 8th out of the last 25.
I don't know which misinformation bothers me more, that the NFC is stronger than the AFC or that Michael Jordan was better than Bill Russell. At least in the case of Russell most people who chime in didn't see him play.
