"The Shark" has won 91 professional titles around the world, including two British Opens, and the game may never see a better driver of the ball.

Tournament golf has fallen off his priority list, as he now operates a multi-national corporation that designs golf courses, bottles decent wine, and makes golf clothes. Quite simply, Greg Norman is still one of the most compelling figures in golf. Twitter would be the ideal platform for the Australian to voice his controversial opinions.
