Djokovic's 2011 was not a great whole season since he crashed in the fall, so he was basically on a hot streak for a few months.
Is Sampras's 1994 season better than Djokovic's 2011 season? Yes or no?
Sampras has multiple slams seasons 4 times and won a slam in 8 consecutive seasons. What about Nole?
Sampras's career is over, while Djokovic's career is far from over. Djokovic is rapidly suprassing Sampras's achievements, yesterday Novak won his 12th Masters (Sampras won 11).
