NFC North CHICAGO BEARS
NFC MINNESOTA VIKINGS
AFC DETROIT LIONS (They play like a lot of AFC teams.)
There are no teams outside of the NFC North I would consider favorite teams to play.
The AFC doesn't matter to me at all. Over the years I recognize some teams have been typically stronger organizations and some are perennial weaklings. Playing them once every 4 years and with them not necessarily coming to GB every 8 years makes it difficult to feel much of a bond. My neighbor is a KC fan so it would be fun to get together for the Super Bowl if they both make it. Other than that I have no reason to favor one team over another.
In the NFC it is a matter of the level of disdain I have for other teams.
Fans from the NFC East are for the most part some of the most obnoxious fans around so I don't care for any of those teams.
