Agreed about players being inspired by Stan's win. I must admit, I was very torn about it. My heart really wanted him to win, and the tennis fan in me knows it's great for the sport to have a different name on one of the big trophies, keeping things interesting. However, my hardened, Andy-fan head knew that the points would make it harder for Andy to over-take him, and give others ideas!
That's one of the things I hate about rankings. You start to want other players to win or lose for all of the wrong reasons.
I've just been reading that Delpo is having bother with his left wrist again, and has needed an injection in it. It's not clear if he'll need to withdraw from any tournaments, but I'd be surprised if he defended all of his 680 points between now and Indian Wells. Ferrer has quite a lot to lose between now and then too, so it's not ridiculous that he could over-take them by then. Unfortunately, with a lot of points to defend in Miami, Andy could drop below them again after that, even if he plays really well.
We have to be prepared for a bit of bobbing about in the rankings, that doesn't really reflect Andy's current form.
