Super Bowl XLVII, between the Baltimore Ravens and the San Francisco 49ers, has the potential to be one of the greatest Super Bowls in recent years -- not just because of the level of play these teams have demonstrated in the playoffs, but mostly because of the story lines all over the field. The 49ers enter the Super Bowl as the favorites, but as you can see by the roads both teams have taken to the big game, there isn't that much of a difference between them in quality. This is probably the best ingredient to make sure Super Bowl 47 will be among the most exciting we've seen in recent years.
