4) Tiger Woods
This pro-golfer saw great success at a young age and most people saw him as a clean-cut, good guy with a picture perfect family. However, in 2009 his extramarital affairs came out, which lead to his divorce and his loss of custody of his children. This, along with some other odd behavior and events, caused him to lose lucrative endorsements, as well as harmed his reputation. He entered therapy and has since been trying to clean up his reputation and build back his career.
