What do you think the careers of either Evert or Navratilova would look like if the other didnt exist? To me it looks like Evert suffered much more from Martina than vice versa. Navratilova probably only lost out on 3 or 4 additional slams to Martina- 1974 French Open, 1982 Australian Open, 1985 French Open, and maybe the 1986 French Open. Evert though lost out on a whole lot more. Wimbledon 1978 and 1979 very likely, Wimbledon 82, 84, and 85 almost for sure. Likely the U.S Open in 83 in 84, and the French Open in 84. The Australian Open in 81 probably. Maybe although these one are a tough call the Australian Open in 85 and U.S Open in 81. She probably wouldnt have won all 11 but an additional 9 or even 10 is very possible. I did consider the semifinal matches between them but I cant think of any where the loser was likely to win other than maybe Evert having a shot of beating Austin in the 81 U.S Open final if she hadnt lost to Martina in the semis. Martina was not likely at all to beat Goolagong in the 75 U.S Open final on clay or the 76 Wimbledon final on grass. Goolagong was the better player at the time and owned Martina head to head around then. Martina also was not that likely to win Wimbledon 1980 as she was clearly out of of shape and form a the time and any of Austin, Goolagong, or Mandlikova (or based on some of her losses that year even the likes of Shriver or Turnbull) could have all taken her out depending how the draw shaped out. Australian Open 88 obviously she wasnt likely to beat Graf. As for Evert her only other slam semifinal losses to Martina were in 87 and 88, and each time Graf would have been waiting in the finals, and her last ever win over Graf was in early 86, so pretty obvious no in that case.
