NFL Playoffs 2012: Ranking Each Team's Biggest Weakness on Championship Sunday

The San Francisco 49ers have a stifling defense and top-notch run game.

The Baltimore Ravens have the most complete team left in the playoffs.

The New York Giants have momentum, experience and a ferocious defensive line.

The New England Patriots have Tom Brady and Bill Belichick.

These are the standout strengths of the four remaining teams vying for the Lombardi Trophy. They all more than capable of winning Super Bowl XLVI and each one of them has something going for them.

The real question is, which team's weakness is the most detrimental to their success?

49ers: Inexperience

From top to bottom, coach to bench-warmer, this team has a very limited amount of postseason experience.

Their shocking upset of the Saints wasn't shocking because of the outcome, but more so because of the way they did it. 

Alex Smith proved he could not only make the big throws, but that he could so with the game on the line. Both he and coach Jim Harbaugh weren't rattled by the task of out-dueling a Super Bowl-winning coach and Super Bowl MVP in their first ever playoff game.

Now they'll have to do it again against the Giants.

But Big Blue is going to come at the 49ers differently, and the Giants expect the Niners to do the same.

We know Tom Coughlin and Eli Manning can adjust with the game on the line; can Harbaugh and Smith?

Ravens: One-Dimensional

Can Joe Flacco beat Bill Belichick and the Patriots' weak secondary? He has to if he wants a shot at the Lombardi Trophy.

The fourth-year quarterback has won at least one playoff game in each of his four seasons in the league, but he has yet to play in the Super Bowl.

His defense is going to do their job and at least give him a chance. Belichick will be damned if the Ravens are going to beat him on the ground.

So again, can Joe Flacco beat propel the Ravens to the Super Bowl with his arm?

Patriots: Secondary Issues

We've seen it all season long and it still haunts New England. Teams that can hit Tom Brady and score points have found a way to beat them—albeit they suffered only three losses.

Baltimore is going to come after Tom Brady, but he's still going to put up points when he has time against a Ravens secondary that really isn't that good.

The question is whether or not the Patriots defense can avoid giving up the big play.

If they can't, they'll have to hope Brady is standing and scoring points.

Giants: Fatigue

Big Blue is the only team alive that played through the Wild Card Weekend. This will be their third straight playoff game—13th straight game if you count the fact that they had a Week 7 bye.

This team certainly has momentum on their side, but flying from the East Coast to the West Coast is never easy. The emotions the Giants have already gone through with their upset win over the Packers in Green Bay has to be taken into account as well.

Fortunately this game doesn't kick off until 6:30 p.m. EST, giving the Giants players' bodies time to adjust.

It certainly wouldn't be shocking to see New York come out flat. The question is whether or not they can battle out of it.

Always chuckin' the rock on Twitter too.
