"I remember several occasions where, after his birthday or Christmas, we had to reprimand him for giving his toys away to kids in the neighborhood," Lilian says. "He was only 5 or so but he said, 'Mom, they didn't have that and I thought they should.' He didn't think to act any differently." Asomugha's e-mail signature also offers a hint. Each message ends with a Bible verse, Galatians 6:9: "Be not weary in well doing; for in due season ye shall reap, if you faint not."

	Asomugha, here with Jamal Jackson, has become a mentor to many at the East Oakland Youth Development Cent

That mindset has stayed with Asomugha, 27, through his six seasons with the Oakland Raiders, and the one-year, $9.75 million contract extension he signed this past summer secured his status as one of the team's veteran leaders. Since his breakout season in 2006, when he had eight interceptions, quarterbacks have mostly thrown away from him. And being on a losing team means Asomugha has worked as of the most underrated cornerbacks in the league -- a lack of attention that's fine by him.

Nnamdi and his older brother, Chijioke -- they are 18 months apart -- grew up playing Pop Warner football and idolizing Deion Sanders. When their father died of a heart attack when the brothers were 12 and 13, "sports were a great outlet for us," says Chijioke, who played cornerback at Stanford.

As a senior coming out of Narbonne High, Nnamdi was a highly recruited defensive back. He chose to play for Cal, where he continued his charity efforts. "My freshman year, I started working with a group called Touchdown for Kids," Asomugha says. "However many tackles I got at safety, [the school would] donate a certain amount of money to help the underprivileged youth in Berkeley. We did it every year and I became the spokesman." When Nnamdi became a Raider as the 31st overall pick in the 2003 draft, he continued the program in Oakland.

During his senior year at Cal, Asomugha had a chance meeting with Regina Jackson, the president of the East Oakland Youth Development Center. The community-based nonprofit Center, which began in 1973 as a job training facility, has transformed under Jackson's tutelage into an educational, academic and recreational haven for children ages 5 to 20. A major distinguishing factor is the Center's hands-on mentality, which puts its youth in operational roles. "My first time there during my rookie year, when I saw the secretary was a 12-year-old and the head chef was a 14-year-old, I was drawn to that style of leadership and wanted to help out," Nnamdi says.

It's not surprising Asomugha would be drawn to a charitable activity that stresses education -- his older sister, Chisara, earned a B.A. from Stanford, a medical degree from Duke and is working on a pediatric fellowship at Yale; Chijioke graduated from Stanford with two degrees and is currently enrolled at Columbia Business School; and his younger sister, Udodirin, graduated from the University of California-San Diego and is working toward a masters in public health at the University of Michigan. Their mother and father both earned doctorates. As the family likes to joke, Nnamdi is the least-educated, with "only" a degree in corporate finance from Cal.

	Thanks to Asomugha, kids were able to take a tour of colleges on the East Coast, including Brown University in Rhode Island.

Asomugha became a regular at the Center, speaking to students about their work ethic or shooting hoops with them after practice with the Raiders. "He's like a friend we've known for a long time, so it's not like we're out here with a Raiders player," says 16-year-old Jasmine Williams. "He keeps in touch with everyone and doesn't forget them, so you know he's really doing it for us and not for the publicity."

Two years ago, Asomugha suggested taking several of the teens on a college tour to Atlanta. He financed the trip for four students, some of whom had never flown on an airplane or visited a college campus. He repeated the odyssey last year, expanding the group to six and traveling to Boston.

While he may be quiet on the field, Asomugha shows his true colors at the Center. "I'm a class clown," he says. "Once you get me in my element, it's bananas." He finds as much enjoyment as the kids, like last June, when he took several students on a two-day fly-fishing trip. Most had never heard of fly-fishing, much less tried it. "I still say it was the best experience of my life," says Jamal Jackson, Regina's 14-year-old son.

"Each year, he tries to do something different," Regina adds. "Last year, he started a holiday party where he rewards kids for academic improvement or excellence. He has fun while emphasizing the importance of education."

Jackson points out that Nnamdi isn't the first athlete to frequent the Center. A portrait of Gary Payton was recently hung above the basketball court, which Payton helped finance with a $100,000 contribution, and Antawn Jamison was a regular visitor during his five seasons playing for Golden State. Still, she says, "Relationships like the one we enjoy with Nnamdi just don't happen. He's a living legacy. He's not waiting 20 years to figure out what he'll be known for. He's doing it now."

That legacy that doesn't stop in Oakland. At his former high school, Asomugha distributes backpacks to the incoming freshmen each year. He also outfits the football and basketball team with shoes, a mandate he wrote into an endorsement contract he signed with Reebok. "Whatever else I can get my hands on in L.A. to help out, I do it," Nnamdi says.

	Times are tough for the Raiders, but Asomugha remains a hero to many kids.

Then there's his family's foundation work. Throughout Nnamdi's childhood, the Asomughas took trips to visit relatives in eastern Nigeria. In a country that ranks among the top 20 in infant mortality rate, the family began providing food and medicine to widows and orphans victimized by poverty or abuse. In 2005, the family officially sanctioned the nonprofit OWIN (Orphans and Widows in Need) Foundation, with Lilian serving as the Director and CEO from her home in Los Angeles.

Dr. Agatha Chukwurah, who helps run the program in Nigeria, describes how the organization tries to visit a different village in Nigeria each month, offering women and children workshops on basic life skills. The villages often have no water, schools or medical help. They bring doctors and nurses to help train the women.

"Our ultimate goal is to help the children and the women and build a stronger center where we plan by the grace of God to be able to do what we know -- we can train them, feed them, see their progress, see them become somebody useful to their self and to the nation," Dr. Chukwurah says. "There are times I cry -- one time, there was a woman with no leg -- a widow with four children -- and she said she came to one of our programs that she'd heard about, and she was so surprised, she said, 'There are other people that even think about us?'"

Says Asomugha's Nigerian teammate Isaiah Ekejiuba, "He does so much for the community here, back home in L.A. ... He's just an all-around community guy, but doesn't brag about it."

That quiet demeanor carries over to the field, where Asomugha lets his play do the talking. "I don't think I've seen a corner with a greater talent than his," says former teammate Jarrod Cooper, who retired in August. "He makes it look so easy that you almost hate him for it. I'm over here running and sweating and he's just taking two steps, knowing where the play is going. He's very smart about the game."

When his football days are over, Asomugha says he's interested in a career in broadcasting or entertainment. For now, though, he'll keep helping wherever he can. "I've always felt that I'm successful for a reason," he says. "So I can help, whether that's one individual or a group of people. That's why I keep going with football. I love the game and I'll keep playing as long as I can, but ultimately there's a different purpose."

Last season, Nnamdi was given the Raiders Commitment to Excellence Award and was recognized by Home Depot for his charity work. "It's in his blood," Lilian says. "You can say your children are good, but you really see when they are little how they'll do when they're older by how they act. He is gracious. That is him."
