Not really. But in an interview with Charlie Rose published in this month in Inside Tennis magazine, she says she is working on something which Roger Federer has already implemented. This might be the "secret" that she was supposed to reveal in RG, as mentioned in another thread. But the interview happened after the Australian, and she has played Miami since then. It seems to have something to do with footwork. According to her, Roger is already doing it, but it was something that Richard has been telling her and Venus to do for years. They could not/did not do it yet. When she saw Roger doing whatever it is, she thought - did my Dad coach Federer? There was talk about Federer "gliding" to the ball. Then Charlie Rose prods her : What is this new thing like?. Reply: Like I am not telling you. Some of her statements like this are like a schoolgirl would talk. Others are more serious, about the heritage of Althea and Arthur. But I tend to agree with the poster who said here that she seems to be not into interviews and gets spaced out at times. Could be deliberate, could be her personality, who knows. But she seems to give Richard too much credit. Did he really come up with a footwork innovation which was also independently discovered by Federer? I doubt it. But Serena is always proving everyone wrong. The issue also has an interview with the Bryans and some insights into their personal life with some comments about girlfriends I found a little weird - you can judge for yourself. One of them is still unattached, so might be an opportunity for the ladies out here.
