Trophies separate the winners from losers, and life is about winning and losing. Go into business and you see. You're competing every day.

When your four biggest tournaments all operate relatively independently, and the ATP and WTA tour operate independently, and you have Davis Cup and Fed Cup that operate independently, it makes it a tough message.

When you lack cohesion, it becomes difficult to have a clear marketing strategy.

I think the Davis Cup has some untapped potential. It should be as prominent as the Grand Slams when it takes place. If you put it together with Fed Cup for an organized, nationalistic team competition taking place in a central location for two weeks, I think that would be beneficial from a fan interest stand point, from a media stand point and from a television stand point.

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

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.

There's a reason why Federer and Nadal are so gracious when they lose. They sleep well at night knowing that they've given their best.
