I find Mary Joe to be a great commentator. She's easy to listen to. She respects the players. She doesn't come off as "little miss know it all" (read Tracy Austin). She doesn't overtalk. She talks about the match. And she knows when to keep quiet.
So my question is: Where are the Producers and what the hell are they doing? Do they never give feedback to these "tennis star commentators?" Because the lot of them just have diharrea of the mouth and ruin it for fans and viewers.
