THEY ENABLE INSTEAD OF HELP
If you have some money, you may have family or friends who ask for loans, handouts or "investments" in their business schemes. Imagine what happens when you have big money.
"Uncles ask for money, aunts, grandmothers, friends, all of the sudden they think it's a free-for-all," Dickerson says.
People demanding money often don't know, or care, what the players' other financial obligations are, they say.
Players should learn to say no, both out of self-preservation and because unearned money breeds dependency, Dickerson says.
THEY TRUST THE WRONG PEOPLE
Some athletes get taken by fraudsters such as Robert Allen Stanford, who is serving a 110-year sentence for a $7 billion Ponzi scheme that snared several pro baseball players, or embezzlers like Brian Ourand, who admitted stealing from four athletes, including heavyweight boxer Mike Tyson.
Others get fleeced by advisers who are incompetent or enrich themselves at the players' expense. Too often, people turn over the keys of their financial lives to others and stop paying attention. Owens wishes he had learned about finances even though he was busy setting NFL records with the San Francisco 49ers, Dallas Cowboys and Philadelphia Eagles.
"That was one of the biggest mistakes that I did is trusting (advisers) to manage my financial portfolio without keeping a close eye on it," Owens says.
THEY SPEND TOO MUCH
Ask anyone who was unprepared for a big windfall - a lottery win, a lawsuit settlement, an inheritance - and they'll likely tell you the money disappeared faster than expected.
Or just ask a typical U.S. worker, who may earn $1 million over a lifetime but fail to save enough for a comfortable retirement.
Athletes can be so dazzled by the money coming that they don't consider the day when it will stop, Dickerson says.
Also consider that what an NFL player is promised in a contract is often far more than he actually earns, Dickerson says, as careers may be shortened by injuries or getting cut from a team.
"Football is a sport that you can play really for three to four years if you're an average player. If you're a great player, you may have a 10- or 12-year career, but that's very rare," Dickerson says.
