Re: Serena and Maria are in the best shape ever
I don't think Serena will ever be as fast as she was pre-2003, but she seems to be better in all other aspects.
Smarter- yes. Better ballstriker, better returner, better match-player? No. That's no insult though. It just shows you how insane her level was a decade ago. She was basically unplayable.
Sharapova still isn't the same player that she was 5-6 years ago.
