To make it in professional boxing you need strength, speed, stamina and some serious box-office pulling power. There's big money to be made and the fighters, coaches, promoters, casinos, sponsors and box-office networks are all receiving paydays of more money than any average person will ever make in their entire lives.
May 2015 witnessed the highest grossing pay-per-view in history; Mayweather vs Pacquiao at the MGM Grand in Las Vegas generated 4.4 million paid views (almost double the last record of 2.4 million for Mayweather vs De La Hoya in 2007) which pulled in more than $400 million in revenue. Live ticket sales came to $71 million, which goes without mentioning was quite a pay day for everyone involved.
Although boxers can make fortunes; they aren't always known as the best financial investors. Mike Tyson earned more than $300 million throughout his career but after blowing all his money on excess purchases such as sports cars and tigers - he filed for bankruptcy in 2003.
Collectively the sporting legends on this list are worth billions; here's hoping they hold on to their money and invest wisely because these net worths would be a phenomenal amount to blow.

"I've seen a lot of broke people who had wealth around me and I paid attention. I know where I came from. I know where my six siblings came from. I know how my mother struggled. It's easy to forget those things when you've been successful for a long time. But I was skillful enough and smart enough to remind myself from where I came. That's the reality check that should keep anybody motivated. We choose which way we go".
