I watched Serena back then too and she was quite an unforced error machine back then her competition wasn't that great back then if she was trumping them all for the big titles. She was a phenomenal competitor back then and played the big points well, but she plays even better than she did now. A lot of times, I would even say she won some ugly looking matches, but she still won because of who she was and what she could do. I just went back to watch a bit of her past matches to compare and contrast then and now. That French Open win was a hideous mess of unforced errors, and she certainly didn't do anything overly amazing but held rather steady to win over her sister. As 2002-2003 progressed, she got it a bit more under control, and she became the force that we know her as today, but Serena has improved drastically in all departments since those days. Her net play was very hit or miss back in the day where as her net play now is much cleaner. Her serve as you said has improved drastically from those days. Now I will admit, her ROS she took larger cuts at the ball than she typically does now, but she is more consistent with it taking her chances when she has to but she gets more in play now than I would say she did back then, her ground game is far more consistent and quite a few less errors. Even back in the Serena Slam days she would have high unforced error counts like in the 30-50 range where as now she has managed to keep it between 10-30. Serena's forehand and backhand are more solid these days. Sure she has the occasional spray match or two, but she is playing within herself and working the points more. I would even say a longer rally favors Serena more now where as back then that was a lot of player's hopes in beating her was to extend the rally because of her impatience. We are just going to have to disagree.
