I have no doubt that he indeed is a very nice guy. But of course he is HUMAN, with all faults and mistakes that we all have.
But it seems he got so used to being the best, no. 1 player in the world, that the past few months his pres conferences were at times strange, his answers not quite polite, his self-esteem publicly over-emphasized...
Have to disagree with you here, quite vehemently so. If anything, I am surprised by the polite way he still manages to handle himself, while he is obviously going through very rough times. He's always been rather honest in his pressers, if not right-out dorky
- that's nothing new. But you'll never see him behave like, for instance, Roddick...
Is Federer able to let go naturally, polite and with a realistic approach for the future, his throne?
Or he will give to the public the "nasty", "darth-vader"-ish side of his personality ?
Like I said, he is no 'god'. None of the players are.
The biggest mistake to make here is not acknowledging that he is indeed a very sensitive and emotional guy, and not at all this 'robot' that some people seem to think he is (used to be a major headcase for a very long time in his career, remember?).
It might very well be that we'll be seeing more of this 'dark' side of his character if his slump continues - and it might be just me, but I think it was already very visible in that match against Simon - he was muttering and even asking some irritating fellows in the crowd to 'shut up'. I don't like it very much, but it is... human, I guess.
As for the way he will continue to carry himself when inevitably having to give up his throne - I have no doubt that he will graciously and wholeheartedly congratulate his deserving successor.
Hopefully he'll be able to find some way, someone, to help him deal with the mental problems he's obviously suffering now.
