How do you blow $60 million in 10 years?

So I am getting my NBA fix when I come across the story of Antoine Walker the former NBA player who played a role in getting my team (Miami Heat) a championship. It is estimated that he earned $60-65 million dollars after tax in his 10 year career. He has blown it all and has creditors knocking at his door. Hello there…can someone explain to me how you can lose that much money in 10 years. Well apparently Mr Walker had a spending habit of someone who thought money grows on trees. I guess no one told him different. See the story on his spending habits here.
