The boxing world lost its best ever boxer the day Ali died.  He had godlike charisma and always backed up his strong words.  Sports Illustrated crowned him “The Greatest Athlete of the 20th Century.”  Like others on this list, Ali died from complications due to Parkinson’s disease.  Doctors attributed the illness to his boxing career.
