Antoine Walker
Walker was a three-time, all-star power forward for the Boston Celtics and Miami Heat and had a pretty decent career, that netted him $108 Million. Then he blew it all on gambling, cars and a personal wizard.
Within two years of retirement he started buying homes in Chicago, filling them with expensive cars and racking up a gambling debt of $822K. Now, he doesn’t have a car and lives on a modest salary as a NBA analyst for an internet sports channel.
