It's pretty much on par with Roger 2005-2008. No matter what the situation in a match, you just expect him to win. Even when he was atrocious in the Simon match, you knew he'd find a way to get it done. Rafa never truly had a consistent stretch like either Fed or Novak, injuries always derailed any chance for him to do that. Ultimately they're three of the top four ever with Sampras. Pretty nice to be alive for this stretch no matter who you think is the greatest.

But I expect Novak to ultimately be the greatest and to break Federer's record, maybe even by a lot. If he stays healthy, he's got 2 more prime years and 1-3 more great years after that. Hard to not see him getting the 7 majors he needs in that time. No one is close right now without playing match of their life type stuff in five sets, and there's really no one on the horizon for a few years unless someone takes a huge leap (like say Milos or Nishikori).
