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

I knew I was the second-best tennis player in the state of Florida and No. 8 in the United States of America when I was 12 years old and I couldn't tell you what I was in baseball, but I liked my chances in tennis of getting a scholarship to college.

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.

If they had rankings in baseball, maybe I would have been able to do the math and figure out my chances of being a professional baseball player versus a tennis player. But that was the decision-maker for me, I just thought I was better in tennis.

Even the poor can be fat in the U.S.

What separates the winners from the losers is that they can deal with doing their best while still coming up short.
