Apparently she's been giving free tennis lessons to under-privilged kids on Mauritius (where she's been living) so "self-centred" doesn't seem to be an appropriate way to describe her now.
Pierce is absolutely one of the nicest and sweetest people ever in the sport. She is an emotive diva when she played, and some people have ridiculous misconceptions of her personality because of that. Even Mary Carillo the b-tch who hardly has a kind word to say of any player said "Mary is one of the nicest people in the sport, a real sweetheart" during her rant complaining about Mary's long bathroom break after the Dementieva semi at the 2005 U.S Open.
She also had to deal with a lot of personal demons with an abusive and nasty father, who used to physically assault her until she was 20.
Of all the ex top players who didnt win atleast several slams, she is probably the one I miss most. She was sexy, entertaining, super exciting to watch when on, unpredictable, yet classy, and had an intriguing back story. And even though she won only 2 slams when she was on, she could literally beat the sh1t out of any player. Who else can do this to peak Graf:
She also has a 6-2, 6-1 win over reigning U.S Champion Serena, 6-1, 6-0 and 6-0, 6-1 wins back to back of Seles and Sanchez to win a tier 1 tournament, and has beaten every top player atleast thrice, with atleast 1 humiliating beatdown of every single one. Here are some more examples of Pierce at her destructive best on her goddess days:
In 1 of her 2 slam wins at the 95 Australian Open she didnt lose more than 6 games or reach even 5-5 in a set in any round, including slam winners/slam finalists Sanchez, Martinez, Huber, Zvereva. At the 94 French she lost a total of 10 games in 12 sets en route to the final, including Graf in the semis, but the rain delay likely cost her the final vs Sanchez Vicario.
