Poll: Who is the new Super Bowl favorite?

Many thought the Green Bay Packers would run through the playoffs and win back-to-back championships after going 15-1 in the regular season. Those that didn’t like Green Bay probably thought the New Orleans Saints had a good shot at winning it all.

But the final four teams remaining were all underdogs to some degree when the postseason began two weeks ago. Now that the stage is set for the AFC and NFC title games, who is the new favorite to win it all in Indianapolis?

Is it the New England Patriots? Quarterback Tom Brady has his team on fire. The Patriots have quietly have won nine in a row and thrashed Tim Tebow and the Denver Broncos, 45-10. Even New England’s defense looks improved in the playoffs.

What about the Baltimore Ravens? The Ravens have been neck-and-neck with the Patriots all year in the AFC and should be a very tough matchup for New England. Baltimore has the defense and veteran leadership -- led by Ray Lewis -- to go all the way. Will the Ravens win it all?

On the NFC side you have the San Francisco 49ers and New York Giants. Both teams upset heavyweights in the Saints and Packers, respectively, for an unexpected NFC Championship Game. The 49ers and Giants are proving that you can still win championships with defense.
