Professional athletes are paid millions of dollars because they are the best people on the planet at what they do and what they do just happens to generate billions of dollars in revenue every year. 

However, with the fame and money comes a lot of pressure to provide for your family (close and extended), friends real and fake, and significant other. Add to that the cadre of agents, managers and financial advisory who see the athletes as meal tickets, and it becomes easier to see how so many end up filing for bankruptcy once their playing days are over. 

A 2009 Sports Illustrated study found that 78% of NFL players either file for bankruptcy or struggle financially once they retire. About 60% of NBA players face similar financial struggles five years after they retire.

Staying on top of your investments is another way to protect yourself. There are countless incidences of athletes being taken to the cleaners by financial advisers they trusted after the funds they invested were either stolen or misappropriated. 

Investment management company Vanguard says the playbook includes "a combination of meeting basic living expenses, establishing a contingency reserve, accounting for discretionary expenses, and leaving a legacy."
