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.

Sports for me is when a guy walks off the court, and you really can't tell whether he won or lost, when he carries himself with pride either way.

You'd have to think that if he'd been around today, Rod Laver would have been Rod Laver.

You can kick a ball into the net, throw a basketball into the net. Tennis is complicated. It'll make a lot of great athletes run the other way because they can't be successful initially.

I think all of us who kind of live within the sport recognize that Davis Cup certainly could be a little more visible if perhaps there were some adjustments made to it, and it was made a little bit more easy to understand for the fans, if there's a little bit more of a start and finish line.

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

If you don't want to practice, unless you have a hard-nosed coach, you don't have to.
