6. Vinnie Johnson – Net Worth: $400 Million
Vinnie Johnson, better known as “The Microwave,” is a former NBA star worth $400 million making him one of the richest basketball players. Johnson became so wealthy after his NBA playing days that he started the automotive business startup Piston Group.

As an entrepreneur, Johnson has vindicated those who argue what former players can do with their skills after the whistle blows, and that even the biggest names can become the biggest in the business.
