Athlete.com has about the most accurate earnings for fighters....

Tyson made 30 million for at least 2 of his fights...To think he made almost 400 million in the ring and has not even a fraction of it....

In truth these guys have a dangerous job and every fight could be their last....

they have nothing to fall back on...EG- 401K, retirement benefits etc so thew risk has to be worth the reward no?
