This notion that the game "has changed so much" since the early 2000s is utter nonsense. When I watch highlights from, say, 2005 to 2010, there is hardly any difference from the game today, except that the overall field was better and more talented. I find it funny how people simultaneously argue that the Top 3 are out of their prime but that the game is better or more advanced now. If that's so, how are they still the top 3? And how are they in some ways more dominant than ever?
Honest question, do you ever EVER defend a position without literally making shit up?
When did I ever claim the game is better or more advanced now? I've always said Federer's generation was deeper and more talented than today's game.
And how are you defining "versatility"? Is it the combination of serve, approach, and baseline game? If so, fair enough. But outside of Wimbledon/Halle (and maybe Basel) where exactly does Federer win matches with his serve, let alone serve-and-volley? Virtually nowhere. And yes, when he does the serve and volley at Wimbledon, it's pretty. But it's not a go-to play on the tour at large. Djokovic and the other player in the top 3 do plenty of effective volleying when they come to net too.
Honest question, do you ever defend a position without a straw-man?
When did I reduce versatility to serve and volley?
Federer has a better ability to break the rhythm with shot variety such as slices and drop shots (and it's not close). His point construction is far more versatile and much less reliant on "V tennis." His serve is obviously much superior (and asking when does Federer win matches with his serve is beyond stupid. He's not Karlovic to win matches with his serve, but his serve, is a HUGE part of why he wins many matches against particular players). Federer, especially in his 04-07 prime, was a simply a better all around player than Djokovic ever was. The combination of first strike tennis, defense, net play, etc... isn't really up for debate. He's got a better touch and it's not even close either.
Djokovic's main claim in this argument is he doesn't get an exploitable shot, like the Federer backhand has been. You can't attack one of Djokovic's ground strokes, and hope it breaks down and that he'll produce some errors. He's a more solid baseliner, and that is huge today, and it would have been just as huge in say, 2005 to be clear. So I don't know what made you think I'm implying the game is that much different today than it was when Federer was in his prime. You literally made a whole post by making an argument up and responding to it. Nice.
But to call Novak flat out more versatile when Roger has a better touch, better volleys, better overhead, better drop shots, better slice, more variety, better serve is just ludicrous. Novak however, has a MUCH better backhand and in a baseline heavy era, that's sometimes a bigger factor than the all the others combined.
