as you said, "in almost every possible way as a commentator/sports journalist."
The good part maybe is that he has been traveling in the ATP Tour since the stone age. He knows a lot of people and provides a good insight on tennis world (especially with the older players). He does have information that other journalists don't have.
The information he has access to is probably the only good thing about him... But I suspect half of the times he improvises
And I heard him make the most disgusting snob comments and he can`t make a coherent comment about a player without stereotyping them..., specially the non-southamerican active players. Sometimes I suspect I know more about them than him....
