You know it was not as limited as we may remember it. She was a better volleyer than either Seles, Graf, Martinez, and a ton of others but we did not see it in singles, in part because her televised performances were mostly in the late rounds of red clay events, when it wasn't prudent to come forward consistently. Take a look at her doubles record and compare with just about anyone on the tour at that time. She won 10 majors in doubles and mixed with 9 other finals on top. She must have been a great volleyer, and must have had more variety in her returns than we saw, or that record just would not look like that. She was limited in heavy hitting weaponry, with no explosive power in her forehand, or a big serve. Otherwise, she wasn't missing much.
