Serena Williams is a tremendous athlete and a great competitor with outstanding mental toughness. She has supreme power and can overpower ANY opponent in women's tennis. That's why she wins. But her unforced errors are painful to watch. I used to watch Sanchez and Graf, Martina and Evert, Seles in her prime. They made so few errors and the tennis was enjoyable to watch. There were long rallies. The winners often tripled the unforced errors. With Serena, it's often either a winner or terrible errors. She plays this brand of power tennis that is hard on the eyes. Yes, she makes some brilliant shots, but her strokes are so inconsistent for someone of her ability and how long she's been playing. She wins so many matches in tight three sets that she should win comfortably in two. It seems one of every two matches she plays, I'm reading about how she couldn't believe how poorly she played, how she has to play better. It's a credit to her ability to play the big points well that she wins as much as she has. But, her inconsistency is ridiculous at this point in her career. Why doesn't she get a real coach and work on bettering her technique? She was unblievably lucky to win the Australian and the fact of the matter is she should be getting better and better--and she's not. In fact, she played much better in 2002 and parts of 2003 than she's playing now. Her groundstrokes are so "muscled" half the time. She sprays forehands all over the place and dumps so many backhands into the net. I don't know if she doesn't work hard enough or is poorly coached--but with her ability and her tremendous mental ability--she should be MUCH, MUCH better than she is.
