I publicly declared Fed would not win another major, so I now concede he may now be tied with Rocket Rod as the most dominant player of all time.
However, this is not all on Fed. Nadal is not what he used to be. Not only has he been doing worse against Roger, he does not steamroll other opponents as thoroughly as he used to. He has dropped off more than Roger.
All I am suggesting is I think this version of Federer would have given Rafa more problems in the past - even a younger Rafa than the Rafa of today. Reason is because the weakness Rafa used to exploit no longer exists. Rafa has NEVER seen Fed hit the BH as well as he is hitting it in 2017. The game-plan a 23 year old Rafa used versus Fed or a 25 year old Rafa used against Fed or a 27 year old Rafa used against Fed would likely NOT work against the 2017 model of Federer. I'm very curious to see Fed's next matchup with Novak. I would pick definitely pick Federer to win the match. There are at least 3 or 4 things that Federer is doing now better than ever - his BH has been en fuego this year. Hitting over it so cleanly and the timing on the BH side has been impeccable. At first I thought it was purely a function of those tailor-made courts at the AO this year but then he did the same thing in Indian Wells - heck he hit the BH BETTER at Indian Wells on a slower higher bouncing hard-court. Fed is also returning serve better now - never his strength in the past despite his all-court complete game. And I believe he is playing the big points as well as he ever as. Brad Gilbert also suggested during the IW and Miami coverage that Federer is serving better this year. The numbers would suggest so.
I think it is noteworthy to point out too that prime Fed in the mid 2000s was not using the new bigger racquet head that he switched to in late 2013. The new racquet has paid enormous dividends - fewer shanks/mishits, more bite on the 2nd serve, he is better able to generate easy power now, etc. Also, this model of Federer is taking full advantage of his front-court skills - prime Fed played primarily from the back of the court. I actually think there is a VERY strong argument to be made that Federer now is more complete than prime Federer. This Federer takes advantage of his front-court skills more and is returning better. The fearhand is as lethal as ever. And if there is a dropoff in the movement I'd say it is negligible. And since he is playing more offensive now any negligible drop off in the defensive skills is almost deemed irrelevant because he isn't being forced to play as much defense these days.
And I think Brad Gilbert could very well be right that Federer is playing the best tennis he has EVER played. So I am certainly not alone in this opinion.
All this said I think this model of Federer has the advantage over Rafa on EVERY surface save for clay. On clay I still think Rafa will beat Federer. My reasoning is below - apologies for the long post but I want to provide reasoning to support my position...
Even with Fed's greatly improved ROS and BH, I don't see how he overcomes a healthy Rafa on clay. Consider this - Fed is beating Rafa on hardcourts the same way Davydenko always beat Rafa on hardcourts - by taking the ball early (especially off the BH side) and using both pace and angles to rush Rafa's FH. Basically, Davydenko could use his BH to break down Rafa's FH, which is exactly what Fed is now able to do.
However, even as Davydenko was dominating Rafa on hardcourts, Rafa was always beating him on clay because the ball moves slower so Rafa can get to every shot (on both his first shot off the opponent's ROS and sharply hit rally balls) AND because the bounce is much less uniform on clay than it is on hardcourts, it is VERY difficult to take the ball right off the bounce without making a lot of errors. Davydenko couldn't do it with an excellent two-handed BH; it would be that much harder to control these balls on clay with a single-handed BH.
And Fed is not going to be able to employ Nole's game plan for beating Rafa on clay, which is a combination of teeing off high balls to his BH (which is right in Nole's preferred strike zone) and out-grinding Rafa. So because of the unpredictable bounce precluding taking the ball super early and the court slowing down the ball allowing Rafa to get to every ball (possibly to hit FHs off the majority of those balls), Fed is right back where he started when he faces Rafa on clay - facing a barrage of high balls forcing him to hit neck-high or ear-high BHs.
I just don't see how Fed overcomes this, which would be even more remarkable to me than EVERYTHING he has done so far in 2017.
As a Fed fan though I am now at the point now where I have gone from dreading collisions with Rafa to inviting them. I feel like Fed can continue to chip away at that H2H now unless a disproportionate number of their future encounters occur on clay.
