I could not possibly root for another AFC team. I'd have to go NFC. I went with the Falcons on a lark, not reading that the thread and thinking it was for this year. But if it was a permanent thing, I'd probably go with either the Saints or the Bears. Probably the Saints.
Oh, and screw the Broncos.
In the final seven games of the 2013 season, the Chiefs averaged 34.6 points per game, scored 38 points or more 4 times, and went 2-5. The NFL has ruined the sport.
