Not that I disagree with Serena being the greatest of all time but I do have an issue with the negative comments of Steffi Graf. I love the fact that she retired before she hit the down slope like someone like Willie Mays and David Ortiz. Steffi could have possibly won another three or four Grand Slams as she only had Arantxa Sanchez Vicario. Steffi retired at the young age of 32. She was a tremendous athlete. I am sure that when Serena beats her 22 GS Steffi will be there because she always had a tremendous amount of respect for Serena. There really has not been a great rivalry since Chris and Martina in the women's game.
