I have always regarded choking as losing a match you were supposed to win. Do you disagree with this view? Because, when Fed was in his prime, his opponents weren't supposed to win very often. Federer was simply the better player and beat his opponents cleanly. Is this still choking to you? And if so, how many of Djokovic' wins last year were due to chokes?
No. I admit Federer was for 2 classes better player then the rest in his era. And he didnt choke a lot cause he was confident and he just knew no1 can harm him. But in course of 4 years of his utter domination he had his chokes or bad moments in GS, and really no1 could use that bad play or chances that Fed gave. If those players were so good as some posters says and not chokers and all super talented they would wait moments like that to steal slam from best player, to get all flamed up and pumped up to win, but in reality they just counter choked and played worse.
Now players arent affraid of Federer no more, and by those players i say Nole and Nadal in GS and occasionaly some1 else, but he is being tested and he is getting defeted. I know Olderer isnt same player as before cause of age, but IMHO his lvl of play atm is still better then any prime player in his era. Im sure he would own them again as 31 yo.
