I definitely disagree with you here. Roger has been too dominant in the past 3 years and blown away too many records for him to be considered a failure because he didn't reach the ridiculous # of 14 GS titles. Even if he only wins the French after this, he'll have GS in the double digits and the Career Slam.
I think it's amazing that he's been able to keep things at the level he has for as long as he has - you really think he'll be able to keep it up until 2009?
No man, I don't think I explained it well enough. From now on, where federer is right now; if he doesn't reach 14 (the later part of his career, now onwards would be somewhat of a failiure). Not his career to date, because that is of course not in question (and the reason why I think he will get to 14 for sure). In other words, I am saying he is too good not to reach 14.
Maybe it's not a failure compared to everyone else, but relative to federer (no question for me that it would be a big dissapointment and shock).
