I mean the Big 3 were the Big 3 for a reason, lol. They have a talent level combined with more advanced racquet and string technology that made it possible for them to not only hit these incredible shots, but to consistently hit them. The guys nowadays sans Sincaraz (and even they don’t fully measure up) have the technology but lack the high end ATG talent to play at the insane level the Big 3 produced.
It’s actually pretty crazy, when you look at the Zedrots and Midvedevs of the world (the two most successful players of their generation) and how meh their FHs are in comparison. Great BHs sure, but the FH will always be the more important, versatile, and offensive shot. That and a huge component of shot making comes from one’s ability to move and get into position to hit these highlight reel shots. Zedvedev move well for giraffes, but their height is ultimately a further detriment to their shot making ability.
