Hell be lucky to last five or six years on those knees. What it might have to come down to is playing less on hard surfaces and playing more on forgiving surfaces.

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.

The dumber you are on court, the better you're going to play.

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.

One of Nadal’s strengths is that he’s so humble, that he’s surprised at what he has achieved, and that he has never bought into his greatness.

What I like about the USTA is that it's developing systems to help the coaches coach better.

The good news is I have time.
