IMO - Federer is getting older - and only -really- now cares about GS titles - (at his point in his career with 13 GS & 1 behind Sampras, nothing else really means too much, not even Masters Series (MS) shields (tournaments such as Doha being even less that an ATP MS on the scale of importance).
Yeah, he still says he wants to win this and that and so on and so forth, but the fact remains the only things that he cares about now are those 4 GS. The rest is just for him by now so non-important that its only natural his performances in smaller tournaments will not have the same spark or desire as when he plays in a GS.
Contrast this to a guy like Murray who is young and hungry for even these smaller tournaments like the 1 he just won. Which is natural, he is young and wants to prove himself.
So when Federer losese to people like Murray and Djokovic and so on, i think having proved in New York that he still has more than enough game to beat either of them over 5 sets on the big stages, one should just remember you cannot expect the same level of effort from Roger in all the rest of the tournaments as he puts into a GS campaign.
I personally don't take it as a shock anymore when I see him lose in some or other non-GS tournament, or even a MS tournament. Stepanek beat him in a Clay MS event last year, and then look what Roger did to him i New York on Arthur Ashe stadium, he took him apart in straight sets. Same goes for Djokovic and Murray in the semi and finals. Bottom line is Roger playing in a GS is just different. That's all you can really say about it.
In general I agree, but I do remember Federer saying in an interview how he doesn't like losing to the same player twice in a row. Also remember the MC match, where Federer played super hard against Murray. Obviously his back was hurting and he served poorly because of that, but still gave it his all.
I guess Australian Open will be a good indicator of Roger's form.
