shut up man...field was weak in 2006 and 2007....I mean Fed was still too good even for todays field but come on
Give a few years time bro, same shit will be said about 2010, 2011, etc. It is always much easier to criticize/praise in retrospect. Either way, all of this shit is completely subjective. While one could say an era was weak, one could also point out that the top player is just dominating more. Just depends what biases you have and how you look at the situation (half full, half empty). There are plenty of arguments people have made about the 70s, 80s and 90s.
Every era is full of clowns as they say.
After all, even if you claim 2005/2006/2007 was weak, Nadal couldn't win a HC slam until 2009. Sure you can say he has "improved" but one could say otherwise about the field as well.
There are always excuses and reasons to make if you are willing to say them.
