Henin was no nobody in 2002 that is a huge knock to Henin in my opinion and makes her sound less of a force than she was. Henin would have done a lot of damage in 2002 French Open had she not been upset so early. Come on she was top 5 in the world, she had been to a slam final and a semi and grabbed her firs tier 1 title that year.
Henin's slam results in 2002:
Australian Open- destroyed in 2 lopsided sets by Clijsters in quarters. This was also pre-prime Clijsters, the same Clijsters Henin would own in Clijsters's prime.
French Open- lost in 1st round to some Kapros girl.
Wimbledon- destroyed in semis by Venus. Still by far best slam showing of year with grass being worst surface, something that could even conceivably happen in her prime.
U. S Open- lost in quarters to Hantuchova
She also wasnt top 5 in 2002, she was top 10. At best she was a very marginal top player, not even one of the top 6 or 7 really. Clearly behind Venus, Serena, Davenport, Clijsters, Mauresmo, Capriati, a past her prime Seles. So she was definitely not in her prime yet in 2002. As for winning her first tier 1 title Henin went on to be by light years the best clay courter of her generation, on another planet from Serena, Kuznetsova, or anyone else on that surface, which surely you will concede. So even clearly not in her prime she can be a major contender on that surface, of course in her prime she is untouchable by anyone of the current generation on that surface unless she is sick or injured.
