"I couldn't believe he threw it and that I caught the ball. I really couldn't believe I scored inside the Coliseum, because I grew up in Los Angeles and I look at people who stepped into the end zone, like Hayes Pullard," says Harris. "It was a big relief with all the stuff I've been through: surgery, hamstring injuries, not starting the whole year, winning a job and taking advantage of that opportunity."
After all he had been through, he stood in a damp end zone, realizing his hard work had paid off.
By now, you probably know the improbable story of the 2016 USC football team -- from 1-3, following a heartbreaker in Salt Lake City, to Rose Bowl champions just a few months later.
While there is no doubting the incredible fortitude, toughness and commitment from this special group of Trojans, those traits are the result of individuals who have stared down adversity and overcome. The journeys of these young men are as endearing and powerful, perhaps more so, than the Rose Bowl victory itself. South Central-raised Harris is one of those men.
"It was rough growing up in South Central, dealing with gang violence. It's something that you just have to be aware of, know your surroundings, who you're hanging out with, what you're getting into, where you're going, who's going to be there, what you have on -- all those things have to come to mind," Harris reflects.
Harris and his three siblings, two brothers and a sister, understand struggle. Their father was in and out of prison. Their mother was a single parent, sometimes working two jobs.
"She's been working hard since I've been growing up, working a nine-to-five job. There's been times throughout my childhood where she had two jobs and still came home, cooked and provided for our family. I appreciate the little things that she's done," says Harris.
While Harris faced plenty of difficulties around 84th and Budlong, his surroundings helped motivate him. He was filled with the desire to work for his mother, for his family.
"I do this for myself because I love the game, and for my family to get us out of the struggle. I want to take care of my mom one day. I'm trying to take care of my family, take care of myself and make South Central a better place," says Harris.
Harris always wanted to play football and saw the sport as his way out. He got the chance to do so at Crenshaw High School, where he used football to stay on a straight path when many of those around him did not. Harris was also encouraged to do so by his father, who helped motivate him when he got out of prison.
"I used to come up to SC and work out most of the time [at the track]. Coming up to SC was time to get away from a lot of stuff going on at home and around my neighborhood. It was a place to feel safe, not be bothered and not have to watch my back," Harris recalls. "I always wanted to go here, so that was my motivation for coming up. That kept me more focused."
While Harris dreamed of a chance to play football at USC, he craved guidance and support on and off the field. He got that from Robert Garrett, the head football coach at Crenshaw since 1988.
"When I was in high school, since my first day checking into Crenshaw, I caught the bus home. By the second day he was giving me rides home from school every day, so I didn't have to deal with gang violence and all that," says Harris, who actually played quarterback in high school. "Now that I look back on it, I probably could have been dead just walking down the street going to the bus stop."
Garrett was eager to help Harris because of the high schooler's dedication.
"What made him special was his ability to want to learn and to study. He always wanted to initiate: 'Let's go study film, let's go study plays,'" recalls Garrett, who moved to Los Angeles from Alabama when racism was prevalent in the South.
"If a kid has that ambition, wow, I'm more motivated than the kid because you don't have too many kids who want to do those things all season. Ajene always wanted to do those things to get better. Whenever a kid wants to get better I take out the time to go all the way."
Garrett acted as a father figure to Harris' fellow Crenshaw Cougar and Trojan, Hayes Pullard, when the linebacker's father passed away. Pullard and many more of Garrett's players have become successful on and off the field, and he doesn't stop supporting them once they leave Crenshaw.
"What I want to do is give them the hope," says Garrett, who always kept a job growing up to help his mother pay the bills. "I like to serve as a mentor to the school to give the kids an outlet, a place to go. If you want to get out of this situation and this area, and do something for yourself, education is the way to do it."
The help and support Harris received from Garrett made their relationship stronger.
"I really appreciate him being that mentor, being able to educate me throughout my high school experience, and have somebody you can look up to as a coach, a father figure and a friend," Harris reflects.
