Money has ebbed and flowed for Mike Tyson for his entire career. He was the biggest star in boxing since Mohammed Ali during the late 1980s and early 1990s, when he seemed indestructible. A career in sport is a short one, though, and when it's all over, you need to have a solid plan to make sure your bank account doesn't suffer the consequences. George Foreman managed to set himself up for life with his eponymous grill. Tyson didn't have any such commercial luck.
We should point out that Tyson is still a millionaire, but the estimated $3m he has to his name is a drop on the ocean when you consider that he was once worth more than $400m. A huge divorce bill did him more damage than anyone inflicted on him in the ring, but he didn't help himself by spending money on lavish purchases like a pair of white tigers, and a gold-plated bathroom. The IRS also took a bite out of him, and frequent legal troubles left him owing millions more to lawyers.
