Twenty years ago, you'd see guys busting rackets in locker rooms. Today they do it in their hotel rooms.

I'm all for a change. There's a lot of coaching that goes on now. I'm not sure I want the coach on the court the whole match, but why not let the player talk to the coach between sets? It gives TV people something to talk about, and it adds to the experience for fans and viewers.

It's not like football where the officials take two or three minutes to review the call. The umpire sees it in 10 seconds, so it doesn't disrupt play at all.

The biggest disappointment of the first round was the four teenagers, who won only one set among them. I could see Murray losing to Juan Ignacio Chela but maybe in five sets, four sets, a brutal match.

I don't know anybody who could take nine weeks off and then boom come back and win a tournament.

He's pushing the envelope, ... All these guys when they turn 30 can say, 'I can work hard and still make it happen.'
