Players need someone who knows the ropes, a mentor, an advisor, an uncle. Enter William Wesley. How's this for a resume? He was right there in Michael Jordan's ear. The whole time. "Wes" helped pull off one of the great feats of modern legend-making. He held the hand of one of the NBA's less likable characters—an angry, cussing, yelling, gambling, adrenaline addict with some sort of over-competitive personality disorder—as he became the most successful pitchman in sports history, complete with his own animated children's movie.

As many different things as you can possibly imagine. There is an entire informal economy available to those few with the power to boss celebrities around. All indications are that dozens of the best basketball players in the world, players like LeBron James, Allen Iverson, and Richard Hamilton, take Wesley's advice very seriously. Players like that are essentially corporations—with the potential to make those around them very wealthy.
