What is the theme of the book Slam! by Walter Dean Myers?

In many ways the theme is individual vs. society and the
individual figuring out their place in society.  Greg is a star basketball player trying
to figure out how to balance basketball, school work, and a relationship with his
girlfriend.  The story revolves around him trying to figure out which one should be a
priority and deciding whether or not to switch schools knowing he likely wouldn't fit in
in the new school.  Of course the entire time he is also dealing with crime and other
dangers in his neighborhood.
