I was always taught that you needed to be intense and never lose your focus.

Kyrgios has got to look in the mirror if he wants to become a top player and win Grand Slams.

If you look at the top 100 players, you would see that the great majority of them have had at least a couple of surgeries. That tells me that we have to protect the players.

There's always a concern when you play the week before a major. That's not the easiest time for a scheduler or a promoter, I would think.

I'm sure a lot of players say it, but winning is almost so you don't lose. The thrill of winning is not as great as the pain of losing.

Why don't they go back to wood racquets? Then we would see the best tennis to be played.

Tennis was a white, upper-class sport, and I wanted it to be treated like other sports were.

The perception is I didn't get along with umpires, obviously, and I didn't, on the court. But off the court, we had a good vibe.

I was always fighting the establishment, trying to run through brick walls.

Things slow down, the ball seems a lot bigger and you feel like you have more time. Everything computes - you have options, but you always take the right one.

I used to take pride if my kids were playing basketball, and I'd be there, and I wouldn't say anything. People were obviously expecting me to yell and scream at the ref and at them and everything. I wouldn't say anything.

You're asking too much of the women. They shouldn't be playing as many events as men. If tennis is best served by women playing events with men, so be it.

Nadal is one of the great champions - a class act.

I can barely remember what I was like 36 years ago when I was 21 years old.

If Roger stopped right now and never won another match, to me he'd already be one of the greatest players to ever play the game. To me, he's the greatest all around talent that I've ever seen.

It seems like the richer you are, the more chance you have of paying less tax.

You can't give away points and games against someone like Murray. You're not going to make it to the top with that kind of effort.

We should reach out to people to try to go after the fans the way other sports do. Because we can't just depend on the fact that it is a great game.

There's a certain beauty and majesty to Wimbledon. The elegance, the way the grass looks on TV.

I've seen tennis clubs close in Manhattan and garages put up in their place, and I'd sure like to be part of reversing that trend.

The greatest compliment I ever got was when people called me an artist, and I understand that solo aspect of being an artist, when you're in there by yourself, trying to do something great, and people who don't even know you can come up and just dump on you.

Maybe I should have played two more Australians and two less Davis Cups? I could have had more majors and still have three Davis Cups when most people don't have one.

With commentating, I've had a chance to show the humorous side of my personality that I didn't use on the court. It's fun, and I don't take myself too seriously. I have good broadcast teams with me, but I'm not a huge stats guy. I think they post the numbers too quickly, and I'd rather let the match play out a bit first.

But these guys learn so fast now, they sort of soak up the information, they're fearless. Those are the guys who learn from their mistakes and come back strong the next time.
