We did say that not everyone on this list went into another profession because they needed the money, and as a case in point, here's basketball legend Shaquille O'Neal. He earned millions of dollars over the course of his career and is one of the very best who has ever appeared on an NBA court.
O'Neal has always had other business interests. He was the star of a video game during the 1990s, and has made a couple of appearances in the world of wrestling. Since retiring he's released rap records, but his most interesting career move was to join the police as a sheriff's deputy in his home state of Georgia. We think if you were ever approached by officer O'Neal, you'd correct your behavior very quickly. He may yet go into teaching - he's been studying in his spare time, and now has a doctorate in education.
