Everybody in the NBA has something to prove.
If you're a bona fide superstar, you're out to show that you belong among the best in basketball, preferably by carrying your club to a championship. If you're a rookie or the backup-to-the-backup at the end of the bench, you're trying to justify your occupation of one of the 450 jobs available in the world's best hoops league.
And if you're anyone in between, well, you've probably got some cause to seek validation in the Association.
