I don't follow Tennis Channel so feel free to share here anything interesting that's said or aired.
As for the footwork, we'll see.
No problem. And I already have before.
For example, when Martina made the comments about Petra not reaching out to her recently, she made those comments, live on the air on Tennis Channel, when asked at the French Open.
As far as Martina's coverage of Petra's, it's quite interesting. First of all, she picked Petra to win the SW19 last year, on Tennis Channel (when Lindsay Davenport admitted on the air, she hadn't even seen Petra play), in case you didn't know. And she was also confident enough to pick Petra to win the French Open last year to. But she had an even bigger focus on the upcoming Wimbledon, after Petra lost to Li Na.
My problem with Martina THIS YEAR was, during the French Open, she'd criticize Petra to high heaven, making sweeping statements, as if she hadn't followed Petra since last year, and wasn't familiar with Petra's injuries, sickness, lack of play, etc., from January till Miami-and Petra's overall game when she plays well. It was akin to a drunken rage of a parent about their child, though she didn't really mean any harm.
Now of course, when asked by one of her colleagues on the same broadcast/match, "who'll be better between Sharapova and Vika", Martina promptly responded "Oh, Kvitova, cause she can volley and has more firepower and variety than the other two".
Translation; I think she really wants Petra to play better and live up to her potential, and she thinks she can help/assist.
And why not!?
We know, as you mentioned, great players don't always make good coaches. But I don't think Martina is campaigning for that. She just wants to be able to assist, chat/catch up with, and be a good, positive influence with the young, developing Kvitova; she of the humongous young, left handed tennis game.
And why not?
