I don't want to sound sexist, but why is Serena Williams the only woman on the WTA with a consistent, huge serve? In the past, Steffi Graf, Monica Seles, Lindsay Davenport, Mary Pierce, Justine Henin all had huge serves. All the men on the ATP Tour or almost all of them can serve big yet the woman cant? I wonder why? What is the difference? Is it due to bad coaching the women are getting that they are not taught that having a huge serve is important? Venus can serve big but her serve is inconsistent, Samantha Stosur has a good serve but she uses the kick too much. I think Nadia Petrova has the second best serve on the WTA Tour after Serena. If Victoria Azarenka is serious about being a great champion I feel she really needs to improve her serve. It is strange to see Victoria a tall strong young woman about six feet tall, in great shape yet she can only serve 107 miles per hour. What is Victoria's coach doing? The serve is the reason Victoria struggles against Serena. Sharapova can serve bigger than Azarenka but she lacks her variety she's too one dimensional. Sharapova is six foot two yet she never players doubles. I think Maria should consider trying to play more doubles come to the net add some variety to her game, slice the ball more use angles ect.
