Hewitt seems to be a popular dude with a lot of players.
I know Federer and Nadal praised him in he past.
he has started a few business ventures. that could be another reason why he is hanging around the sport. he wants to keep his name in the spotlight.
I have noticed that he is popular at these forums also.
I never followed him back in his day so I am not really sure how good he was. guess he is known for his fighting spirit and the also the fact that he was the youngest world #1.
