Djokovic has now officially entered the rarified air of all-time greats in men's tennis with this victory. 64-2 in 2011, 3 Major wins, 10 titles overall, and it would've been a Grand Slam, except that he ran into a vintage Federer at the French Open. There's no doubt in my mind he would've beaten Nadal there, too.
Nadal had a dazed, bewildered look in his face during the trophy ceremony. It almost seemed as though he was about to cry. No one has ever owned him this badly, and he's probably wondering what's going on. Djokovic has the exact same mental edge on Nadal that Nadal has on Federer. This is pretty amazing stuff, and as Don said, we're lucky to be watching these great players at the moment.
Novak has a style that is somewhere in between Nadal's and Federer's. So, it's safe to say he can stay relatively injury free during the next 3-4 years, and at only 24 years of age, should have no problems winning another 6 majors to reach double digits.
And if this level of dominance continues, then he, and not Nadal will take aim at Federer's record. If I'm not mistaken, Roger had 6 majors by the time he was 24, so Djokovic needs a similar year in 2012 and then it becomes a very real possibility.
