Michael Jordan is the only billionaire athlete in the world, I'm pretty sure he is the anti-example of what you are trying to convey. Use Latrell Sprewell or Allen Iverson instead.
Maybe "entrepreneurial success" would have been a better phrase (as douchey as that word can be). While his licensing, branding, and endorsement income has been huge, his attempts to start up businesses of his own have been less than noteworthy successes.
