NEW ORLEANS (USA TODAY) -- Long before this duel of brothers in Super BowlXLVII, John and Jim Harbaugh got pregame-style pep talks from theirfootball coach dad on the way to school. Dino Paganelli and his twobrothers dressed in black-and-white stripes for Halloween to be liketheir officiating father. Peter Hansen sat in the rain as a toddler towatch his father coach Jim Harbaugh as a high school quarterback.

Now, they're all here to participate in the NFL's ultimate game.

Footballin the blood? Parental role modeling? Personal choice? For somefamilies, it's a mix of all that, and the stories of how they got hereflicker like old home movies. For them, football goes far beyond tossinga ball around the yard or sharing chips and salsa on Super Sunday.

Inthe past, we've seen quarterback brothers Peyton and Eli Manning, sonsof former NFL quarterback Archie, both win Super Bowls. Then there arethe Stoops brothers - all four were coached in high school by theirfather, and all went on to become college coaches.

Right now, theHarbaughs are football's first family. Jim's San Francisco 49ers playolder brother John's Baltimore Ravens in the first brother vs. brotherhead coaching matchup in Super Bowl history - the Har-bowl.

ParentsJack and Jackie, both in their 70s, live in the Milwaukee area. Theywon't be wearing 49ers red or Ravens purple. You win some, you lose some- in bowling terms, they're guaranteed a split. They got a taste of itin 2011 when the Ravens beat the 49ers in the regular season.

"Thatthrill of victory and the agony of defeat, and on Sunday night we'regoing to experience both of those great emotions," says Jack.

"We're going to hug both of them," Jackie says.

Thebrothers will take the field with full tanks of competitive fire. Jackcoached them up on that when he was at Iowa in the early 1970s and theboys had sad faces as he drove them to elementary school on coldmornings. "We will attack this day with an enthusiasm unknown tomankind!'' Jack, who coached in high school and college more than fourdecades, would say.

Says John: "My dad's leadership style as a coach was enthusiasm. ... He was a go-getter, the best motivator I've ever heard.''

Jack always told the boys that they keep score for a reason, so play to win. Now, the parents await the score.

CarlPaganelli doesn't care about the score. His son Dino will officiateSunday as the back judge. His other two sons, Perry and Carl, also areNFL officials. Both have worked Super Bowls.

"I'll be watching the officials more than I do the game," says the father.

Asan assistant coach with the 49ers, Peter Hansen will be on theoutskirts of the Harbaugh spotlight. It took Hansen a while to catch thecoaching bug, but this is also a milestone moment for him and his dad,Earl, still the coach at Palo Alto (Calif.) High.

Others decidedlong ago they would be coaches. When Bill Belichick was in junior highin Annapolis, Md., he helped his late father Steve, a longtime assistantat Navy, pore over game films and prepare scouting reports. Belichickhas won three Super Bowls as coach of the New England Patriots.

InYoungstown, Ohio, four Stoops brothers helped their dad and coach, RonSr., set up the projector at home, too. Now, Bob Stoops is coach atOklahoma, where Mike is defensive coordinator. Mark is the new coach atKentucky. Ron Jr. is an assistant at Youngstown State. In 1988, Ron Sr.suffered a fatal heart while coaching a game. Ron Jr. was an assistantfor the opposing team. This is a classic football family, too.

Butjust because football is the family business doesn't mean you have tojoin the firm. Jack Harbaugh takes no credit for instilling coachinginto Jim and John.

"I don't know if we instilled anything, but Ithink they watched. They observed and they saw things that they liked,''says Jack.

Bo and the boys

Deluged by interviewrequests, Jack and Jackie held a press conference this week in a packedballroom at the media center. They said they viewed the attention onthem as a tribute to all the parents of players and coaches in the game.

Butthey're a family in which one of mom's pet sayings is "one game at atime." Says Jack, "If I had a dollar for every time I've heard her saythat."

The Harbaughs met while students at Bowling Green in Ohio.Jack played football. He was getting started in high school coachingnear Toledo when the boys were born 15 months apart in the early '60s.Jack figures they moved 17 times in his 43-year career, which includednine college jobs. He calls Jackie "the rock." She sold and bought thehouses and got the kids in schools.

Jackie tutored players attimes. Daughter, Joani, younger sister to the boys, became an expert atsplicing game films. "I didn't know I was in a coaching environment, Ijust felt that was how we lived,'' says Joani, wife of Indianabasketball coach Tom Crean.

The boys absorbed all of it.

"Ithink everything that we are as coaches goes back to when we were kids,"John says. "So (it was) not so much about watching Super Bowlstogether. ... Growing up as Jack Harbaugh's son, who coached for severalyears at the University of Michigan for Bo Schembechler, that's whatmolded us.''

Jack's seven-year run at Michigan (1973-1979) came asJim and John were approaching junior high. The boys roamed the lockerroom. The practice field was their playground. They had all thewristbands any kids could want. Sometimes, they wrote the No. 7 ofthen-star quarterback Rick Leach on them and sold them at school.

Jack credits his wife with bringing the boys to his work.

"Shewanted her children to know what they're father did," Jack says. " ... Ican remember when they could just barely walk. ... They were piling updummies and they learned they could throw the ball around.''

Duringhis stints at Iowa and Michigan, players would come to their home forThursday night dinners. "Jackie would cook a great meal for them, andthen pretty soon they're wrestling on the floor (with the boys)," Jacksays.

Jim recalls a 1970s song, "Cat's in the Cradle," by the lateHarry Chapin, about a son longing to be like his dad. The son asks,"When you comin' home dad?" The dad responds, "I don't know when, butwe'll get together then son."

But the song was about a father who was never around. Jim Harbaugh said that was the opposite of his dad.

"Whenwe were growing up, my dad would play catch with us, he would take usto games, and most of all he believed in us. We grew up just like him,"Jim says.

After starring as a quarterback at Michigan, Jim was afirst-round draft pick of the Chicago Bears in 1987. He played in theNFL until 2001 and went into coaching. After winning stints at theUniversity of San Diego and Stanford, he landed the 49ers job twoseasons ago.

Jim set his path in high school: "His goal was after playing as long as he could, he wanted to coach," says Jack.

After John's playing career at a defensive back at Miami Universityof Ohio, the family wasn't sure which field he would choose. Law schooland politics were possibilities. Jackie was excited about that.

Butone night at dinner, he told his mother he might try coaching. "Towhich Jackie went face down in the mashed potatoes," Jack says.

Jackieclarifies that. "There were no mashed potatoes," she says. "I saw thatlook in his eyes and my feeling was, 'You have to do what you want todo.' ''

John joined Jack's staff at Western Michigan as a graduateassistant (while living at home). He worked his way up to an NFL job asa Philadelphia Eagles assistant. In 2008, Baltimore called.

Thebrothers' teams have rugged lines on both sides of the ball. Jack andSchembechler liked that. Both teams pound the defense with the runninggame. Jack says football is "blocking and tackle and running andchasing."

But the Harbaughs aren't carbon copies of their dad.When Jack was coach at Western Kentucky (1989-2002), Jim always wantedhim to pass more.

"I think there was one time where he called apass when I was at one of his games," Jim says. "And it did work. Itwent for a touchdown."

Dad made the calls

CarlPaganelli, 73, of Wyoming, Mich., officiated high school and collegefootball for about three decades. He officiated in the United StatesFootball League and World League. He's been a supervisor of officialsfor college conferences and Arena Football.

His three sons are NFLwhistle blowers now. Perry is 55, and Dino is 45. The other son, alsonamed Carl, is 52. They live in Michigan, where as kids they showedtheir stripes.

"They used to dress up as officials for Halloween.We used to play out in the front yard, and everybody was an official.The kids, they would make calls and things like that," says Carl (CarlT. in the family to distinguish him from son Carl).

Injunior high, they started going to high school games he officiated. Ondrives home, they asked about calls he made. They all played high schoolfootball, but they also got into officiating as teens.

"TheCatholic league used to play on Sunday. We would go to mass and aftermass go right outside because the football field was right there andofficiate," Carl says.

Sons Carl and Perry officiated Super Bowl XLI together in Miami in 2007. Carl has worked three of them. It's Dino's turn.

"Dinois working a Super Bowl after six years in the NFL. It's quiteremarkable what these young men have accomplished in their lifetimealready," says their father, Carl, who will be at the game with hiswife, Mary.

The Paganellis have dealt with suffering and loss.

Dino's wife, Christy, died from melanoma in 2011 at age 40, leaving Dino and three young children.

Son Carl's wife, Cathy, recently completed chemotherapy for cancer. The family says she is doing well.

"Duringthe hard times the boys were able to always officiate. That's the waythe girls wanted it," says their mother, Mary. "The NFL officiatingfamily is a very special. They have done so much for our family. Theirsupport has been overwhelming."

Dino'schildren are Brady, 13; Jake, 12, and Katelyn, 5. Their grandfathersays Brady and Jake are getting to know the rule book.

"It'sremarkable - after being around dad and their uncles and grandpa so muchtalking football - what they know about things like pass interferenceand offensive pass interference," Carl says. "The little girl is insoccer and softball. ... You'll see more Paganellis coming up in a numberof years in officiating."

Mary and Carl have a ritual. "When theofficials come out of the locker room, we hold hands say a silent prayerand just feel how lucky we are and so proud of what the boys havedone," Carl says.

Drawn to coaching

Peter Hansen doesn't recall specifics from Jim Harbaugh's playing days under his father, Earl, at Palo Alto High School.

"Iwas going to the games as a little 2-year-old," Hansen says. "Thestrongest memory I have is that the rivalry games was in a downpour. Isat with my mom under one of those clear painter's tarps."

Afterplaying football and basketball at Arizona, the 6-foot-8 Hansen playedfor a pro football club in France in 2003 (the Cannes Iron Mask). Heplayed basketball for Club Falcon in Copenhagen, Denmark, in 2003-04.

InDenmark, he did some youth basketball coaching. "We had to coach theyounger kids in the club. I was kind of forced into it because I wasthere. And then I started feeling like I liked it," he said.

He hadn't grown up itching to coach.

"Allmy life, people asked me if I was going to coach like my dad," and Ialways said no," he says. "But then that experience, I guess it kind oftriggered the coaching bug in me."

He returned to the USA to coachfour years under his father. Family networking helps. Hansen became astrength and conditioning intern at Stanford under Harbaugh in 2008.

"That'show I got my foot in the door," says Hansen, who later became aStanford assistant and moved with Harbaugh to the 49ers two seasons ago.He does video work with the defense and runs the scout team, simulatingthe Ravens this week. Now, he's in the Super Bowl. His dad and mother,Marilyn, will be there.

If the 49ers win, the Hansens will celebrate. Jack and Jackie Harbaugh know their deal is different.

Jackalso points out that Jim's oldest son, Jay, works for uncle John as acoaching intern with the Ravens. He's doing video work and assistingwith strength and conditioning.

"You've got father and son competing against each other on Sunday night as well," says Jack.

But the marquee match-up is Jim vs. John.

Jacksays his sons had one request of their parents: "Both of them haveshared this with us: 'Mom and dad, please promise us that you will enjoythis, enjoy this experience. That's all we're asking."
