At least for now, the NFC is light years ahead of the AFC.
Patriots Defense, terrible, Denver D, middle of the road, Chiefs D, terrible, Indianapolis D, terrible. The best teams in the AFC are pretty much offense oriented. The best teams in the NFC (Seattle, Carolina, San Francisco, New Orleans) are built around great defenses and have QB’s with great skill sets.
The NFC looks like it will win a couple more Superbowls before the AFC catches up to it....
