Here you can't list all of Navratilova's accomplishments,for example, to summarize and define her greatness. YOU just pick one simple sentence and defend it as the greatest reason to appreciate her. I'll start. Evert reached the semifinals of 51 grand slam events out of 55 entries as a career achievement, including grass,clay and hard court slams. from the age of 16 through retirement at 34. These are the events that obviously have the best draws, the most players and the most inspiration. This includes all those early career slams when champions are learning their craft, how to compete, those slams a player might be injured, ill or burned-out, or just in a horrible draw, or in the midst of a personal crisis and in decline. She performed an incredible feat of career long consistency that will never be equaled. ONE STAT or fact that best defines a champion and his/her legacy.
