No, the problem is that Federer himself and the fans here often make cheap excuses, there are only few posters like you who analyses matches correctly and takes loss as they are.
Well that goes for the most of fanbases, I think.
If Fed had indeed had a chance in those two final sets, or had been playing badly, blew his chances, or whatever, I'd surely have pointed it out (
). Fact is that he was just totally outplayed by Isner today.
There's never any harm in just admitting that the other guy was the better player on the day I think. Same goes for Fed's loss to Tsonga in Wimbledon last year. No excuses, just the better player won, and congrats to him.
Thanks for your kind words btw. Much appreciated.
