I agree. And because you have to go through the top 4 to win slams that makes winning slams much more difficult today.
If the current Novak was playing pre-Nadal he would still beat Roger most of the time and would be winning slams everywhere, probably the GS too. But the question isn't fair of course because the way Novak plays is because he had Roger and Rafa to inspire him.
