Yes the Ravens won it last year ( But if it wasn't for some Buffalo Wing janitor, throwing the light power switch off for 30 minutes. The Niners would have won it ). Who are the AFC contenders ? Well, you have Brady, Manning, Flacco, Rothlisberger. Its going to be a decade since the Patriots won it. Going on 7 for Peyton, and when the Steelers had to play a really good team ( Packers ) they lost. The NFC ? Giants Packers, Niners, Saints, Seahawks, Falcons. ( Any of which would win it any year )
