The weird thing is I saw shades of not only Novak, but Rafa and Roger as well. It was just moments, specific shots...it was like he was switching from one to the other. He really is a phenomenal talent. He's the only one of NextGen where I have a feeling that "this guy could be truly great." None of the others--Zverev, Tsitsipas, Shapo, Kyrgios, etc--look like potential all-time greats to me. Zverev is close, and I expect Tsitsipas to win multiple Slams, possibly Shapo, but they all questions around them - elements of their game and/or mentality that limits their upward potential, in my opinion. FAA seems to have it all.
