28. Adrian Peterson
Peterson is the classic example of an NFL star who made a fortune but couldn’t pay his debts. Furthermore, he is also a great recent case study. Before he lost all of his money, Peterson was worth about $100 million. Obviously, that’s a lot of money to squander, but somehow he managed it. Throwing birthday parties with 320 guests, ice sculptures, and camel rides probably didn’t help.

Of course, a $100 million contract doesn’t take tax into account. In 2019, he failed to repay a $5 million loan, and the interest piled up. It resulted in a messy court battle after the bank called in their debt. Peterson trusted the wrong people and paid the price. Luckily, he was still an active player so he can make some money and be wiser for the future. If he was retired it could have totally ruined his life.
