Let me get this straight. Kournikova's lack of success as a singles player and her failure to live up to the expectations her, and others, had for her, is now considered as belittling her? Fine, she won 'plenty of doubles championships' and yes, pit crews can make the difference, but to compare the number of variables involved between winning a race and a tennis tournament, directly or indirectly, its not even a contest as to which has a limitless number of possiblities of things that can go wrong.
