UFC fighter Pat Barry was thanking his lucky stars for his big win against Antoni Hardonk. The fighter won a $120,000 purse for his accomplishment, which was right on time given that he was literally six days away from being evicted from his apartment. Barry's win was emotional for obvious reasons and nearly everyone in his camp was in shock to hear about his financial situation. What is saddest is that his challenges are not uncommon among fighters in general.

Although Pat Barry hasn't had the chance to earn millions, many major fighters end up going broke even after their gravy trains have stopped flowing. The outcomes don't make any sense, given that a bit of financial discipline could have made all the difference in the world. When you earn as much as $10 - $20 million dollars in a payday, you can live a pretty wild financial life and still have money to save. Instead, some athletes seem to want to push the limits and it's actually uncommon to hear of any boxer who DOESN'T end up in the poor house.

Here are a list of financial demons that plague fighters when they finally hit the big time:

1) The bling: For some reason, athletes and entertainers are expected to live an incredibly extravagant lifestyle. Mike Tyson employed over 200 people and spent millions on items too ridiculous to mention. What's worse is that Mike Tyson actually owed as much as $38 million dollars at one point. Evander Holyfield's $10 million dollar, 54,000 square foot mansion was put on the auction block last year after foreclosure. Many athletes go into debt because they are banking on their next payday to get them out of the new financial holes they keep digging for themselves.

2) Bad relationships: Divorce is a great way to go broke. Before Muhammad Ali married his third wife, Lonnie, his previous wife divorced him and took his last $2 million dollars right before Muhammad's career ended with Parkinson's disease. It was at that point when he found himself broke and unable to earn additional income. Fortunately, a good woman came into his life and used her MBA from UCLA to liquidate the massive financial value from his brand name. So, as much as black male athletes can be ruined by women, they can also be saved by them. However, a long string of baby's mamas, bad marriages, draining relatives and expensive arm candy can cost an athlete dearly.

3) The IRS: The IRS is sneaky and has led to the financial demise of many celebs. Even honest, hard working Americans can fall prey to the demon of back taxes. Joe Louis was one great example of a man who made a great deal of money, but found out years later that he owed tax money to the IRS. For the rest of his career, he would wander from one fight to another, with IRS agents waiting in the back room to take the entire purse after the fight. While his career was a great one, he was not a happy man in old age.

4) A lack of education: A lack of money management ability and inadequate financial literacy plagues many wealthy entertainers and athletes. Growing up in poverty doesn't exactly endow you with an extensive understanding of trust funds, estate planning, stocks and bonds. One of the great tragedies for NFL and NBA athletes is that many of them attend universities that simply hand the athlete a degree without forcing the athlete to get an education. But there is an old saying that "a fool and his money will soon part ways." Even if you are incredibly wealthy, you have simply made yourself into a sucker for those who are smart enough to take that money from you.

5) The leaches: The easiest way to get a pack of new friends is to have a lot of money. In addition to the friends who suddenly find you to be a fascinating human being, you've got managers, lawyers, agents, homeboys and baby's mamas who want their cut. It is not uncommon for a celebrity to have to give away as much as $700,000 out of every million dollars he/she earns. Everybody wants a piece of your pie until you are down and out; at that point, you become yesterday's news.

I don't think that any athlete should live like a miser, that's no fun. Instead, why not simply save 20% of your income and party with the rest? That would give you a nest egg for retirement and allow you to pay the bills after you've fought your last fight. What's saddest is that every boxer says they are going to retire young and none of them ever do. It's time to stop living the same story over and over again.
