Colts moving from the NFC to AFC after losing to the AFL as the NFL representative probably tops the same division Superbowl. Since they weren't in the same division with the Saints or Bears, that was a miss. I am not sure if they were in the same division with the Cowboys prior to moving over to the AFC. I will have to go check that out.
I also don't remember which division the Bucs were in when they spent 1 season in the AFC prior to switching back to the NFC. Since the Browns have never been to the Superbowl, no chance of them playing a team from their old NFL days (though in reality, it would be the Ravens organization that played in the NFL pre-NFC days).
Sorry for doodling with this thread. kidhawk's post got me to thinking out loud.
