There is no luck in this sports. You earn everything good or bad. Novak paid his dues. He lost his share of close matches. He just have the steeper learning curve.
Talking about luck, if Nadal was born the same year as Federer, Roger could have been one slam wonder and Nadal could have had 30 GS titles.
If Nadal was born the same year as Federer, we'd still have courts playable for normal tennis and not sand speed and may death tear them apart...
ATP would have done the necessary to have a solid rivalry, so the slam count might have been different, but with 1-2, not more imo.
About the luck, you still need some dose of it in single points playing against absolutely equal to you adversaries.
Remember this full swing return against Roger at the USO? The flawless drive volley, this Rafa passing shot, those consecutive BPs against Murray - statistically you can't make them, it takes a bit of luck imo.
For example there was no such situation involved in his loss to Roger at RG.
So Nole together with being hyper strong mentally in all those moments, kinda had fortuna with him as well.
I realize that you need all the guts and talent, and physical form, and everything, etc. to get there to be in position having this kind of situation first, so it's no bashing or trolling, just i was thinking how close he was losing in both his last matchs at the AO and remembered his USO dramas with Roger, so was interested in others' opinions.
