Well, yeah, we naturalised a PF. Considering our second PF was Saša Zagorac, that considered a retirement in 2013 since by than, he barely earned for a living playing basketball and than got convienced to play one more cash-less season for fun, which turned out decent enough for the man actualy getting paid for almost the first time in his career... of course we naturalised Anthony.
But there's a thing.
Give me 10 210cm kids (better said kids that are promising to grow to such height) and 10 years of training... half will probably be stiffs, 2 will end up playing basketball for free, 2 could make a pro career (unless the country is loaded with such height, meaning they won't get through as easily) and 1 of them might likely get into a consideration for NBA level at some point.
Let's got to PF's... 20-30 kids around 205 cm, 80% won't make it, some will play at amateur levels... and 1-2 might develop into a decent european level.
SF's... 60-70 kids of aprox 200 cm potential height... vast majority won't make it, few will play recreational in lower leagues, 2 or 3 might make actualy earn a buck or two and 1-2 might potentialy develop into a servicable wingman at higher levels.
Now let's go to guards... basicaly out of 100 technicaly very good kids at pretty early ages, within the selection process it basicaly comes down to having luck and being injury free at really early ages for them to even get noticed and pushed a bit further, where their talent will be judged all over again. I remember when I was 14, the competition on SG was tremendous and differences between them relatively small. Potentially some that didn't get the chance could even use it better than the ones that were pushed forward, be it injuries, club politics or temper issues coaches didn't want to handle, not to mention a lot of them didn't get the same amount or quality of the practices, let alone coaching.
That's the enviroment that makes it possible to grow a guard star. Deadly competition that requires enormous devotion, as well as luck, for those kids to make it. Sure, those top notch potentials can get noticed pretty early, but it still takes the enviroment I described above, for them to fulfill their potential.
As much as some won't like to hear that, that's also the reason USA's let's say 300th best PG is still good enough to be naturalised by some european NT's and be considered almost as a cornerstone of that team.
Now... we did naturalise a 211cm tall PF, a really good one while we're at it, but I don't really care about it that much, at least we weren't forced to naturalise a PG, as most countries do. Than I would be deeply worried about my countries bball future. Some might have a big base of 200cm+ tall guys, that aren't really that hard to develop when you put it through the numbers game perspective, guards can be a bit different story.
Respect to the countries that don't get into the naturalisations, however while naturalising a C / PF might be a numbers game, the need of naturalising a guard is in my opinion much worse as it's an indicative of a much bigger issues that take a lot of time and effort to resolve.
