It's an argument that he's at least playing 2nd best this season. He's only played 3 events.
I am sorry but he is not playing "second best" as you said, otherwise he would be number 2 in ATP race. Which he isn't.
That's false and I'll tell you why:
If you only consider the 3 tournements he has played, thn nadal is still the second, because they both reached the semis of Australian Open and Indian Wells, but Nadal did better on Dubai.
So tell, who is teh second best? Still Federer?
Think about it.
