#2: Roger Staubach
Roger Staubach is considered one of the best quarterbacks ever to play American football. He played quarterback for the Dallas Cowboys for 11 seasons in the 1970s, leading the team to five Super Bowls and two Super Bowl victories. He won the Heisman, was named the Super Bowl MVP, and was elected to the Pro Football Hall of Fame.

So when you hear that he has a 600 million USD net worth, you probably assume it’s because of his sports career. But that’s not entirely the case! He started a commercial real estate business in 1977 because, as he told D magazine, “They didn’t pay quarterbacks what they do today.” The business was hugely successful, giving him the financial security that his football career failed to give him.
