Transcript for Blind USC football player walks the field one last time
Finally tonight here, our person of the week. A boy defying the odds to reach his dream. He's inspired millions, including us and our friends at ESPN. When we first met Jake Olson, he was 12, battling a rare form of eye cancer. But he was still on that field. Jake had already lost his left eye at ten months old. But the cancer had returned, and he would soon lose his right eye, too. We fought so hard, and yet cancer wins. Then it's like, well, I'm gonna experience something that no one else can experience. I said, "Jake, how you doing, buddy? You okay?" And he goes, "Yeah, mom." He goes, "You know what," he goes, "This is just gonna be a new stage in my life." Reporter: A major usc fan, they invited him on the field when they heard his story. All right, go get them, guys. Reporter: In fact, Jake was at their practice the night before he would lose his sight completely. Everything's gonna be all right, man. Reporter: But he never gave up hope he'd play. This is Jake years later, in high school. And as I started thinking, you know, what position could I play that, you know, wouldn't require me to have sight. Then I came upon long snapper, Reporter: In fact, his high school team would help him with signals. I clap so he knows the distance that I am. So I use that as a directional source. And then the left guard taps Jake's leg, and it's whenever Jake wants to snap at that point. Reporter: After high school, he would play at his dream school, usc. And he did it again. Reporter: And just this past week, Jake walked onto that field one last time, his dad with him. So was his guide dog. Jake Olson. He's all smiles. Reporter: One more chance for the fans to cheer on that boy with a dream. And so we choose Jake Olson, a young man who taught us never to give up on that dream. Good night.
