You're probably right about those two. Could rob a Masters or two. Zverev imo would've won in Rome, but Raindal showed up again batting like .995 for his career after rain . Zverev won't ever face him early enough at the FO for him to worry about. Maybe in 2019 or 2020 someone can put it together. Might be Djokovic. Tsitsapas another one with a chance maybe.You had me until the third sentence. RG'19 denadal is dependent on a healthy and lengthy continuation of the Joe Kovic resurrection, perhaps a resurgent Wawrinka or some serious maturation of a NextGen star without the scar tissue of Thiemrev, the equivalent of the Ozzian Scarecrow and Cowardly Lion with one lacking a brain and the other missing a heart.
One of these kids has to produce on clay sooner or later. I was hoping it was Kuhn by 2020 but his ankle injury just wasted a whole season on the dirt. Tsitsipas is now on the edge of Top 30 but that lopsided Nadal final in Barca put him in a tailspin. Maybe just the one mauling doesn't leave a mark. I'm pressed to mention any others...flaws, flaws everywhere flaws.
