She was never really a top, top player. The year of "the bump" was her peaking, or, you could say, of a flash in the pan. A little bit like Jonas Bjorkman, who made it to, I think, 4 in the world, but doesn't really have the talent of a top 5 player. I don't want to call it a fluke, but I think they were merely incidents of playing above themselves for a year or so and then playing back to their natural level.
As for Spirlea, she didn't really have a killer instinct and her mobility was a major weakness. Also, she got married soon after her best year and probably had family as priority over her career. She was known to be emotional and have a cussing problem. I think she was one of the only women to be defaulted. I don't know how many women actually were defaulted in history, but I remember she was certainly the only woman that year. Though, I don't think these things mean she was a bad person as I've read/heard several times that she was actually one of the most popular people amongst the tour.
as for the "fucking Venus Williams" comment, she simply meant that she thought that Venus was arrogant and acted as if she was better/bigger than everyone else.
