Djokovic:
R128: Ymer
R64: Berankis
R32: Hurkacz
R16: Khachanov
QF: Bautista Agut/Berrettini
SF: Medvedev/Tsitsipas
F: Nadal/Thiem
^This is a joke draw. On a hard court the potential Hubert, Hatch, QF trio could be pretty cool, but on clay? I also have a hard time believing either of those two guys will even make it to the semi final. If Nadal had this draw there would literally be 50 threads about what a joke it was already. Between the draw, the balls, the time of year, roof and night matches, this guy has to be heavy, heavy favourite in a way almost as overwhelming as 2016. Hoping Carreno comes though that section and gives us the rematch of the century in the quarter final.
Nadal:
R128: Gerasimov
R64: McDonald
R32: Evans
R16: Fognini/Isner
QF: Zverev
SF: Thiem
F: Djokovic
^I'd imagine/hope it'll be Nishikori in round 3 rather than the disgruntled hobbit, surely? First two rounds are the walk in the park he'll probably be glad for given his lack of time on court so far, but after that (including Fognini, not the first man to ever take him 5 at Roland Garros) I'd say it's about as hard a draw as you could put together on a clay court that doesn't include Nadal himself (give or take Schwartzman)
Medvedev:
R128: Fucsovics
R64: Ramos-Vinolas
R32: Basilashvili
R16: Lajovic/Rublev
QF: Tsitsipas/Shapo
SF: Djokovic
F: Nadal/Thiem
^This guy has never won a match at Roland Garros. If he gets his first this year I will be surprised if he goes too much further. I could see him losing any of those matches, and even if he strings together a few with his experience I can't see him making it past Rublev if that mad ******* holds it together long enough to make it to the 4th round to begin with.
Thiem:
R128: Cilic
R64: Opelka
R32: Ruud
R16: Wawrinka/Murray/FAA
QF: Schwartzman
SF: Nadal
F: Djokovic
^Cilic is a shell of the player he was a few years ago, but still, this is definitely the toughest out of all of these from top to bottom. Wouldn't be surprised to see maybe Koepfer in round 4, though the prospect of Stan and Thiem at Roland Garros could be pretty tasty if they're both healthy. Still, what a draw

when your easiest (only easy, really) opponent is the guy who will probably knock down double digit aces and could take you to a couple of breakers you're definitely going to have to earn that Prince of Clay tag.
Bonus-
Zverev:
R128: Novak
R64: Herbert
R32: De Minaur
R16: Goffin
QF: Nadal
SF: Thiem
F: Djokovic
^Imagine starting with Novak and ending with Djokovic!

Seriously though, another pretty tough draw that could definitely test him. I could easily see him losing to Herbert, and I'd have him as second favourite to Goffin, tbh. Could easily seeing that going five and Nadal (assuming he doesn't run into Fabio on one of the days he decides to care) feasting on the winner.
