Here's how:
* Max's interest: Max, the narrator, is a fan of basketball, specifically mentioning his love for the Lakers and Magic Johnson.
* Kevin's abilities: Despite his size, Kevin possesses impressive athleticism, including being able to dunk. He even tries out for the school basketball team, but his size and lack of coordination prevent him from making the cut.
* Symbolic representation: Basketball serves as a metaphor for Kevin's desire to be accepted and included, despite his differences. His attempts to play basketball highlight the challenges he faces in fitting in.
Overall, basketball is not a major plot point, but it is a minor aspect that helps to reveal Max and Kevin's personalities and the social barriers they face.
