Tennis is still very successful in spite of itself.

We lose a lot of young athletes because tennis is such a difficult sport. It's not like kicking a soccer ball.

I think there's no reason the Davis Cup couldn't be as powerful and popular and profitable as any of the four majors are today, given some changes.

The good news is I have time.

I am there to play tennis and represent the U.S., but I'm also aware that not everyone's going to be able to think that way.

There used to be a lot more politics in the Olympics, when the Soviet Bloc committed a lot of resources for propaganda purposes.

It's really easy to find your friends when you're playing away. You have a close-knit group with you and everyone else is cheering hard for their side. There's more satisfaction coming away with a road victory.
