I have a tape from Acura 2001, semi-finals, Venus vs Lindsay. Venus needs to watch that match over and over again to see how she was serving, and how she was hitting her forehand. Even her motions seem different.
And also she needs to go back to her mindset of 2000/01 when she looked like she was out there for the fight! She should stop looking so apathetic and lost. Perhaps it is time to take time off like she did at the beginning of 2000. A sparse schedule wont help. She needs to go away, hire a good shrink, and work on that forehand and serve. In 2001 she was belting winners with that shot, and she did have tight matches, but she never quacked!
