The way the NFL works, your enemy is your division first, then your conference, then the other conference. Therefore, when you make a trade, the last team you want to help out is somebody in your own conference. This has resulted in an interesting cycle of power where every ten years, each conference takes turns winning nearly all the superbowls of that decade.
In the 90’s, the AFC won 8 out of 10, while in the 90’s, the NFC won 7 out of 10.
So, my questions are:
Will the pendulum swing the other way in the next decade?
If so, which AFC teams will become dominant forces?
