hmmmm... Kralingen agenda present but unclear... will continue to observe situation as it unfolds...
of course, famously, sub-ATG elite players of previous generations have not had glaring weaknesses in their game that they never truly patched up. Jose Luis Clerc must have been very unlucky to not make a major QF outside of RG, because obviously he had a complete skillset.
no one would ever argue John Newcombe's success was contingent on his improving his backhand and return, rather than polishing his serve, volley, and forehand strengths
the first complete top player in over a decade is an ATG... you're so close to getting it...
ah there we go, it's just repackaged "social media gen ROFLMAO."

combo of these two seems like the most reasonable explanation. the inverse would be Spain becoming a great tennis nation with a lot of good forehands, footwork, and shot selection because of the clay training and coaching. a sort of medium spot would be Russia churning out a bunch of players with great backhands because they play on indoor hard courts, and unlike Canadians their coaches recognize the incentives of the modern game and do a better job training fundamentals. fwiw a lot of top American men actually have very good or elite backhands, along with the usual serve success that can probably be partially attributed to our throwing sports. that's more recent than the same (less nation-specific) pattern on the women's side, so there may be an interesting story to tease out of gender separated but converging American developmental pathways.
hmm there might be something to look at with Lendl vs Navratilova and their evolving diet and fitness as they grew up and moved to America?
this isn't necessarily true. you can imagine a world with many times more ATG talents playing professionally than currently, if structural barriers (of which tour structure is one) were lessened significantly. the flip side of seeing an ATG talent "make it" is a dozen potential ATGs not making it for various reasons, inherent to the sport (injury) or not (financial support). you can think of it like general return points vs break points: if you get lucky you can cluster return points for a break no matter how bad you are at returning, but being a systematically better returner increases the likelihood that you break through. since we're dealing with the incredibly small sample of world class pro male tennis players among the incredibly large sample of aspiring pro tennis players, it's a lot harder for a nation to simply get lucky with even just one ATG.
