-Federer winning Wimbledon and getting back to no 1, also winning 3 Masters which is almost as many as he won in 2008-2011 combined.
-The fact that we had 4 different major champions instead of 1 (or 2) which made the season very interesting
-Nadal missing 6 months of the season which pretty much means that he won't get back to the top 2 until 2013 is done and dusted
-a new face that could mess up in the rankings next year - that is Janowicz
-blue clay introduced which was a fresh experience
-Nadal being upset by Rosol
Least favorite parts:
-Djokovic being screwed up in the French open final, he was in the middle of an epic comeback before they had to stop
-Federer losing the Gold medal match at the Olympics
-The fact that players ranked 8th and lower have absolutely nothing to say against the top guys
-The fact that the tour is still mostly a grindfest. Is it too much to ask to have at least 2-3 big tournaments where you don't have to grind to win?
Just shows you how pointless H2H's are. Nadal beat Fed but in the end it meant jack, they both walked away with nothing. It's about winning titles.
