Look at the statistics of 2012 US Open final :
Winners = 40 for Djokovic - 30 for Murray
Unforced Errors = 65 for Djokovic - 56 for Murray
At the net = 39/56 for Djokovic - 16/24 for Murray
The most defensive player won, it's sad...
The future of the sport is defensive tennis. The slams keep getting slower and slower.
