I agree. I think it comes down to the "idea" of talent, which in the tennis fandom most people seem to associate solely with racquet skills. I see talent as a bigger package, i.e. having a strong work ethic is a talent - I sure are shi*t don't have that. Not becoming a mess at clutch time, good shot selection, natural fitness/endurance, capacity to surround yourself with a good team, take coaching advice well - I boringly see it all this stuff as talent.
Did I overrrate Shapo's talent? It seems like it, yeah. At the end of 2019, and even in 2021, he was getting close to the top and seemed like he was moving in the right direction. He's still pretty young, and might have a strong late career, but right now he's got to figure some stuff out for himself.
