That is far more coincidental than Steffi having 8 of her 12 major final misses of the 1987-96 decade in the 2.5 years from mid-1990 to 1992.
No, this has been explained sooo often in the last 25 years by Grafans:
Seles had a 56-6 win/loss run in the first 15 months after her return.
2 of those losses came in the USO 95 & 96 finals against Graf (who was in peak form again!).
With Steffi in her usual form of the early 90s (when Seles racked up all those slam titles) Seles would have won those two USOs.
Which would given her a 58-4 win/loss run - a better winning percentage than in her best year 1992!
No, Seles went down starting at the end of 1996.
Only
then the trauma theory had to be developed. Since Seles had become a US citizen by then and Graf was threatening Navratilova‘s GOAT status the US media went to work.
