I actually thought that Novak has a few Djokovic-specific speed bumps in his. A few guys in there who have beaten him, on clay, even. Fucsovics could be his second round, and, while he's never beaten Novak, he's a tough customer. I don't expect anything from Cecchinato, should they meet, but he is the guy who upset Novak at RG in 2018 (when ND was still coming back from his walkabout.) Then, as was mentioned above, Foki looms, and he beat Novak last year in MC, his calling card upset. RBA is in there, and if he gets Rublev, Andrey beat Novak in the final in Belgrade (clay) last year. Not saying he won't get through all this, which is all presumptive, but as has also been mentioned, Novak is looking more vulnerable than usual coming into this Roland Garros, and there are a fair few guys in there early that might feel some confidence facing him.
I thought Alcaraz's section looks very friendly, though, at least until and if he meets Novak.
