Since entering the NBA at the age of 20, Shaquille O'Neal has been a man among boys. His power, skill and size have made him close to unstoppable on the court, and his ability to achieve success beyond basketball seems boundless as well. Second only to Michael Jordan as the king of endorsements, the 7-foot-1, 330-pound center has released five CDs and starred in several movies.
