Lee-Waters' Boy, are you saying that you have seen recreational players who were better than NLC? I have seen plenty of very talented amateur players who would never even dream of playing in proper tournaments.
Just out of interest I pulled Nancy's WTA/ITF stats for the past few years:
2003: 8 tournaments entered, 0 wins, 8 defeats, total games won: 2
2002: 18 tournaments entered, 0 wins, 18 defeats, total games won: 8
2001: 16 tournaments entered, 2 wins
, 16 defeats, total games won: 33
Her wins were 6-1 6-2 over Becky Brown (who has a similar record to Nancy) and 6-1 6-2 over Karen Fodera, another Bagel Girl.
Looking back at her results, it really does make you wonder why she keeps on playing matches at a level where she is going to lose 6-0 6-0 almost every time. She can't possibly make a living at it, and surely it is more satisfying playing in a local club league or something where she stands a chance of winning at least a set from time to time. Maybe she's a masochist. Maybe she likes to boast about the level she can 'play' at. Maybe she has too much money, loves tennis, and plays these kind of matches just because she can. By the way this is a woman who will celebrate her 42nd birthday this year, so you can't expect too much of her against today's bright young things. Maybe she wants to keep her game in top form so that, like me, when she reaches 65 she can win a veterans' Grand Slam.
You could argue that in every tennis match there is a winner and a loser, so for every player like Serena with an incredible winning percentage, there must be someone at the opposite end of the spectrum with nothing but losses. But 6-0 every time? That's just a player who is out of their league, and bear in mind that the events she enters are only $10k and $25k challenger qualifiers.
Personally I think it's kind of sad, although I can see how easy it is to get into a habit of losing, and accepting it because you were playing against stronger opposition. You soon convince yourself that it's more worthy to lose against pros than to win your local tennis club's annual tournament.
It's a fascinating subject (in a car crash kind of way), and hopefully someday we will know the answer (I would definitely buy a Loeffler-Caro autobiography if she decided to write one!)
