You really want a tough draw for Rafa. It can be done even with the current folks and with ranking considerations of draw.
1R: Coric
2R: Tsitsipas
3R: Verdasco
4R: Fog
QF: Novak
SF: JMDP
F: Thiem
Even the above draw does not mean that Rafa can't win RG. But, surely it would make life difficult for him. You are acting as though all draws are same, that is not quite true.
p.s. The above draw is consistent with the seedings these players have.
A quick point first: the first 3 rounds are irrelevant. Nadal on his worst day isn't losing to the guys you mentioned so it really doesn't matter. I don't even take them into consideration when factoring in the difficulty of his draw.
Nevertheless, that definitely would have been a tough draw, but it's almost literally the only tough draw. If you keep exactly the same names, but put Novak in the other half, all of a sudden it's not THAT tough of a draw. It's a draw with a tricky potential 4th round match-up and that's it (and only gets interesting in the semis, which is going to happen in reality anyway).
So your argument is proving my initial point: How many draws would you look at for Nadal at RG, and honest to god go: "Rafa has a tough draw"?
So no, I'm not acting like anything, and I'll spell out my argument again: The good thing about Rafa's draw is Novak is in the other half. And like I said, proof is, in your draw above, put Novak in the other half and all of a sudden it's an interesting draw but that's about it. So yes, I concede that Novak being in the other half is good for Rafa, but some of the names that were being thrown around as proof as to why Nadal has an easy draw (which again, HE DOES. I never disputed that), are ridiculous. Wawrinka, Goffin, Dimitrov, Nishikori...There's a reason they got bounced out early. And again, I ask, what chance would you have given each one of them to even take a set off of Nadal? I'm serious, can you give me a percentage? And after that, what's the percentage of them winning?
So for the final time: Nadal's draw IS easy, but unless he played Novak in the QF, and Novak has a vintage day, there was never a chance of him losing before the semis in any draw. Like almost literally no chance. Incidentally, his opponent in the semis will likely be the same one you listed in your hypothetical tough draw above, and his opponent in the final could well be the one you listed. Meaning, again, it boils down to Djokovic... Because i'm sure you don't really think Coric, Tstsipas, Verdasco and even Fognini had a chance (though the latter would be at least interesting).
