Muhammad Ali is often credited as the greatest heavyweight boxer of all time, as well as being widely recognized as one of the most influential sports figures of the 20th Century. From his flamboyant trash talk to his flashy footwork and the Ali Shuffle, he clearly has had an impact on the sport. Many of today’s boxers mimic the moves and boxing techniques he pioneered during his reign as heavyweight champion. With wins over Joe Frazier, George Foreman, and Floyd Patterson, he certainly achieved success in an incredibly talented heavyweight era. That, coupled with his political activism and innate charisma, served to make him well-deserving of his nickname “The Greatest”.
