Mary Carillo saying something should already serve as ample reason to render it void. If you trusted her wisdom Venus and Serena would be playing in the French Open final every year, Coria beating an old Agassi on clay would be the equivalent to Chris Lewis having beaten John McEnroe in a Wimbledon final, and Mirijana Lucic was going to be the more likely next phenom of tennis over Hingis, Venus, and Serena.
For the record here are Graf's head to heads with non-Seles opponents from start of 1987 to mid May 1990, from mid May 1990 to mid May 1993, and from June 1993-end of 1996:
Graf vs Sabatini: 15-3 from start of 1997 to mid May 1990, 6-8 from mid May 1990-mid May 1993, 5-0 vs Sabatini from mid May 1993-end of 1996
Graf vs Novotna: 7-0 from start of 1987 to mid May 1990, 9-3 from mid May 1990-mid May 1993, 10-1 from mid May 1993 to end of 1996. Graf's only loss ever Nototna other than the THREE 1991-1992 losses was by retiring after the first set due to injury in a match.
Graf vs Sanchez: 6-1 start of 1989 to mid May 1990, 13-4 from mid May 1990-mid May 1993, 8-3 from mid May 1993-end of 1996.
Graf vs Navratlova: 6-2 from start of 1987 to mid May 1990, 1-2 vs mid May 1990-mid May 1993.
Wow isnt it amazing how Sabatini and Novotna were all mysteriously playing so much better during the early 90s than they would anytime before or after. I mean they had to in order to be way more successful vs a Graf "playing better than ever" in the early 90s, who supposably would not improve any further as well. This despite that Novotna began having her best results by far in the mid to late 90s to boot. Isnt it also truly amazing how Martina suddenly began doing alot better vs Graf in her mid 30s than she had vs even a teenaged Graf when Martina was alot younger.
To put some things into perspective Novotna had the best accomplishments of her whole career in 1998 and yet still went 0-2 vs a Graf who was so injured that season she only played 2 of the 4 slams and had losses to Serna Appelmans, Kournikova, Sugiyama, in limited tournament play. She then lost her final ever match with Graf in their mutual final year on tour (a career which for Jana ended in a flurry and for Graf with a sputter) with a 6-2, 6-0 spanking. So despite that Jana lost all 20 of their matches that were not in the mid 1990-mid 1993 time span, and while having the best years of her career at the very end of the decade still went 0-3 vs an injured Graf who was losing to journeywomen, Jana still amazingly managed 3 wins vs a Graf "playing better than ever before" during the early 90s. Fascinating indeed.
Also incredible how Navratilova from age 30-32 fared much worse vs Graf in the late 80s than Navratilova from ages 34-36 would fare vs the Graf "playing better than ever" in the early 90s. That must have been some amazing transfusion of energy the aging Martina got, like something you see in a Sci Fi film perhaps Even more amazing Martina even while still in her prime in 1986 and 1987 would have a worse W-L ratio vs a 16 and 17 year old Graf than Martina aged 34-36 would have vs a Graf "playing better than ever".
The one exception to all this is Sanchez Vicario who mantained a quite similar head to head in the early to mid 90s. However one must delve a little deeper. From mid 1990 to mid 1993 Sanchez beat Graf in straight sets on 3 different occasions. After mid 1993 or before mid 1990 Sanchez would never win a match with Graf in straight sets. One of those straight set wins included a 6-2, 6-0 thumping for Sanchez Vicario, while the best she would fare in any other time period vs Graf would be winning 6-4 in the 3rd set. Sanchez also never beat a healthy Graf on a non-clay surface any other span other than mid 1990 to mid 1993 (Graf had a serious back injury aggravated while leading midway through the 1994 Canadian and U.S Open finals). Yet in 1992 and early 1993 she twice beat a fully healthy Graf on hard courts, and in 1992 did so in straight sets, interestingly her only ever straight sets win over Graf on hard courts, something she couldnt even manage on clay at any point outside the mid 1990 to mid 1993 time span.
Monica Seles was certainly not the one that caused Steffi to be struggling so much that she lost before the finals of 9 of the 12 biggest tournaments played in 1991 and 1992. Last I checked Seles was not on court when Graf was losing 6-0, 6-2 to Sanchez Vicario in a French Open semifinal, losing to Zina Garrison at Wimbledon, losing to Jana Novotna on slow hard courts at the Australian Open, lost to a 34 year old Navratilova in a U.S Open semifinal, lost in straight sets to Sanchez on fast hard courts in a U.S Open quarterfinal. You will have to enlighten me further to how Seles was the one that caused Graf to be losing at any of these tournaments in such embarassing manners.
Anyway it looks like there are stats that support a theory that Graf indeed was NOT playing particularly well at all for her standards those 3 years, let alone "better than ever", at a level higher than ever before and which she would improve no further on either (according to many of your recent comments). You counter that by having Mary Carillo on your side. Errr ok.
