Why the 49ers Will Win Super Bowl 47

San Francisco head coach Jim Harbaugh is the younger of the coaching Harbaugh brothers, but had the better playing career of the two.

And now he's threatening to upstage his older brother in the category of coaching.

In the early Super Bowl XLVII betting Jim's San Francisco 49ers were favored by 3.5 points over John's Baltimore Ravens. And why not?  [ Matchup Report | Game Preview | Why the Ravens can win the Super Bowl ]

With their new-found juice on offense and their usual stinginess on defense, the Niners are looking awfully good right now.

Here are five reasons San Francisco should win its first Super Bowl title in almost 20 years two weeks from now in New Orleans.

The NFC Always Covers

The NFC is 5-0 ATS in the past five Super Bowls and they have won four of those games outright. So with the 49ers facing just a 4-point spread, there is nothing to suggest they can handle that spread and win both ways (for fans and for bettors).

Some experts believe this game will be a blowout with the aging Ravens defense unable to handle Colin Kaepernick's size and scrambling.

The Ka(e)ped Crusader

In nine games this season with Alex Smith at quarterback, San Francisco ran a competent but unspectacular offensive attack that averaged 23 points per game. And the Niners went 6-2-1 this year with Smitty behind center.

But in nine games with former Nevada Wolfpack-er Colin Kaepernick at QB San Francisco has gone 7-2 and averaged 28.5 PPG.

Kaepernick looked like an absolute wizard in the playoff win over Green Bay, then calmly brought the Niners back from an early 17-0 deficit in the NFC championship game on the road in Atlanta to a 28-24 victory.

Kappy is big, very mobile and apparently too young to realize a guy with nine career NFL starts isn't supposed to lead his team to the Super Bowl.

Plenty of Gore

Like a good horror flick, there will be plenty of Gore in the Super Bowl and the question is whether that stout but aging defense can handle it. It could be a horror show for the Ravens.

Frank Gore is the type of workhorse that can wear down a team in the second half, especially when the linebackers need to spy on a mobile QB.

Little Brother's Revenge

Older brothers always hold a certain edge over their younger brothers, but older brothers also know that as time goes by, their winning percentage goes down. Sometimes little brothers go on to grow larger than their big brothers.

Sometimes they even become more successful. You can bet your ass little brother Jim relishes the chance to go against his big brother once again, after all those backyard brawls of years ago.

On the Field

But enough about the Harbaughs. They are an incredible story, but once the game is kicked off it will be their players who decide the outcome.

If San Francisco wins, it will be because Kaepernick keeps his cool, makes wise decisions and doesn't  turn the ball over. It will be because Frank Gore and the offensive line grind out 120-130 yards on the  ground.

And it will be because the Niners' third-ranked defense puts the clamps on the Joe Flacco-to-Anquan Boldin passing combo, which has accounted for three TDs in these playoffs. 

Of those three items, Kaepernick's play carries the utmost of importance.
