WHen i said choke i ment in general. Tho you have the point, but dont u find it strange that Hewitt and Thugbandian suddenly who owned Fed untill 2003 from that moment on never beat Federer again on slam? Did Federer rised so much and changed this game from that 2004 and those 2 failed badly?
Fed's level improved dramatically from the Masters Cup 2003, it was a shock quite like Djokovic's 2011, except that it kept on lasting for longer.
Meanwhile some of these players had problems.
