2012 Niners won in Atlanta and Ravens won at NEBot the Niners and Ravens had good defenses and solid running games. Rams have a very good run game but a crappy defense. NE has an good run game and a solid defense. I can't see both of them beating teams with a decisive home field advantage. But NE would get the edge.
This was the thread i was looking for. I am very confident both road dogs makes it to the super bowl this year. Not only it is considered the “the year of the dog” both teams are good enough.
