(CNN) -- America has spent $12 billion getting ready for the big game Sunday. Now it's time to cook the wings, prepare the dip, order the pizza, put the beer on ice.
The San Francisco 49ers are favored to win their sixth NFL title, but can the Baltimore Ravens send their magnificent, but controversial, linebacker Ray Lewis into retirement with a second championship ring?
Will the Baltimore defense be able to stop young quarterback Colin Kaepernick from beating them with his right arm and his legs?
Who will win the battle of super siblings?
Who will have the best commercial? Will it be sexy or funny?
Will the halftime show be live? OK, Beyoncé assures us it will.
Here are five other story lines you might be talking about around the snack table before the game kicks off in New Orleans at 6:30 p.m. ET:
1. Some fans are 'Switzerland'
Indiana Hoosiers basketball coach Tom Crean will be one of the 72,000 fans at the game.
But he and his wife, Joani, and her parents won't be pulling for the Ravens to maul the 49ers or for San Francisco to knock off Baltimore.
You see Joani's brothers, John and Jim Harbaugh, are the two opposing head coaches in the big game. John coaches the Ravens, Jim leads San Francisco.
"I get, 'Which brother are you rooting for?' " Joani told the New York Times. "I'm sure it's a joke. I'm neutral. I'm Switzerland."
In a perfect world, Jackie Harbaugh would like to see the Super Bowl end in a tie, but she and her husband, Jack, know they will have one son on Sunday night who'll be ecstatic and one who'll be melancholy.
"There is going to be one winner and there is going to be one who is going to be totally disappointed," said Jack Harbaugh, who coached for 43 years." My thoughts go to that one that will not experience the thrill of victory. That's where our thoughts will be."
And mom and dad, married for 51 years, will be there to make things a little better.
"We're going to hug both of them and tell them how proud we are of them and their teams," Jackie Harbaugh said.
The old coach said he was just as proud of his sons this week as he was in the days when they each told him they made the junior high or high school football team. Or when they said they earned a college scholarship -- Jim to Michigan and John to Miami University in Ohio.
"The thrill that you feel -- I know this is on a big stage -- but in parenting, those don't rank any differently," he said.
2. "Reverend Ray" inspires, draws criticism
At Pastor Jamal Bryant's church, God is on the Ravens' side. And why not? Bryant is Ray Lewis' pastor, the man who helped lead Lewis to redemption.
People at the Empowerment Temple AME Church call Lewis "Reverend Ray." Bryant says the title fits.
"He's a jack leg preacher without a license, no Bible college, but it's just in him," Bryant said. "He's spoken here a couple of times, I've put him up to do our Bible study, and he's like Billy Graham and Bishop (T.D.) Jakes wrapped into one."
Fans say Lewis' in-your-face faith and extensive community service is beautifully sincere. His critics find it phony -- a redemption tour with no true redemption.
"Redemption? Stop acting like you are one of those people that come out of the Bible," Greg Wilson told CNN.
Thirteen years ago, Wilson's nephew, Jacinth Baker, and his buddy, Richard Lollar, were stabbed to death outside of an Atlanta nightclub.
Lewis and two others were charged in their killings.
Four months later, Lewis pleaded guilty to misdemeanor obstruction of justice. A jury acquitted Joseph Sweeting and Reginald Oakley. "It was self-defense for me because someone attacked me," Oakley told CNN.
Today, Lewis insists whatever happened in Atlanta changed him.
"With everything I've been through in my whole life, the thing for me to be here today and my only purpose in life is to find ways to help people and encourage people and make our world a better place," he said.
Bryant compares Lewis to the biblical figure King David.
"David was a man after God's own heart, after committing adultery, after committing murder, after being negligent on the job, after being taken out of position," Bryant said. "He's still somebody who God honored, and I think that many times history can't appreciate it while you're in it, it's only after you walk away."
That is the definition of redemption, Bryant said. It's not what you've done, it's what you've become.
3. From starter to mentor
Alex Smith can't help but be a little disappointed even though the 49ers are in the game of their lives. Just a few months ago, Smith was San Francisco's starting quarterback before a concussion sent him to the sideline.
Kaepernick, the second-year backup, played even better than Smith, stayed in the lineup and had a big role in getting the 49ers to the Super Bowl. He said Smith has been supportive since losing his spot.
"It means a lot," Kaepernick said this week. "I think it really shows his character and the
