This is something I haven't figured out and I've wondered about this on a few occasions. I tried looking at it from this perspective: * Evert popularized the two-handed backhand in the 70s which was then duplicated by Austin. However, Austin went down with injuries which pretty much left Evert to carry the 2HBH. Even though she was VERY successful, most of the up and comers were using one-handed backhands. King, Goolagong, Navratilova, Mandlikova, and a host of OHBHers still predominated the landscape. * After Evert retired, it would be a few years before another 2HBH player would rise. While that was waiting to occur Graf achieved the Golden Slam while Navratilova and Mandlikova were in the slam mix. Seles and Sanchez-Vicario emerged. But after Seles got stabbed, that really left Sanchez-Vicario holding the fort for the 2HBH while Graf went on to win a ton of slams. And the OHBH camp also had Sabatini, Novotna, Conchita, Sukova as possible successors to carry Navratilova's torch. * Things for the OHBH camp started going downhill as Graf was on the decline. By the time she left, 2HBHers Hingis, Serena, Venus, Davenport, Pierce, Capriati were primed and ready. Meanwhile, the OHBHers had to wait until Henin and Mauresmo emerged. What baffles me is when exactly did the 2HBH start to become popular for on the WTA? Graf was winning 3 majors a year in the mid 90s yet when she was on the way out, the vast majority of new stars were using two-handed backhands. Did Seles' success ignite the rise of the 2HBH? Were coaches drifting towards teaching the 2HBH to women despite Graf's success? Was it because girls were starting to play tennis at a younger age in the late 80s and early 90s which resulted in a huge wave of elite women with 2HBHs once Graf retired? I'm NOT trying to start a 2HBH-OHBH battleground as we have enough of those already. What's happened on the WTA as far as the OHBH is concerned is something that almost defies logic.
