Perhaps you're thinking of:
* Junior Battle, a real-life player on the 1999 Richmond High School basketball team (the real-life team on which the movie is based). He was a key player on the team but not a main character in the film.
* Kenny "Worm" Battle, a main character in the film. He is a talented but troubled player who struggles with his academics and personal life.
Could you please clarify who you are referring to?
