What exactly are you arguing?
You can't dispute the claim about the average players by mentioning that "there are" some taller
Meaning: in average great players are shorter, even though there are some taller than 185cm...
Look, the US could become great in soccer, but not just for the reasons some people have mentioned, mainly the athletic ability of black Americans (for those reasons only I don't see them top Brazil).
In the meantime African countries are making huge improvement in coaching and resources, and they already have the culture and some star players. This improvement is real, not imaginary...
With more nations playing the sport at the high level, in the future it will be even more difficult to dominate anyways...
Btw,
this is an interesting article about increased injuries, but it gives an idea about the physical requirements to play the sport:
According to further research, a footballer runs at least 300 kilometers per season. That’s like running about 7 marathons. Some midfielders run more than 360 kilometers per season, which are 8.5 marathons.
According to top cardiologists, runners should do “just one or a few” marathons or full-distance triathlons. Their conclusion is that “over-exerting the heart for years can lead to long-term damage.”
This explains the increased number of
heart attacks on the pitch, which I used to connect only to doping.
For everyone afraid of US football health damages and believing that professional soccer is safe, read it. The modern game is becoming really dangerous for the heart and for the legs:
I see many feet and legs problems in marathon runners and many problems caused by trauma in Rugby. However, footballers seem to suffer from both problems. Traumas and erosion. Footballers are damaged like marathon running Rugby players. For them, at a young age at least, it doesn’t matter. They want to play as many games as possible. I, as a sports physician, need to fix them for the short term but I know the damage is long term”. Ben-shoshan, who works for PSG, adds: “I think that players can’t play more than 20-30 games per season and stay healthy”.
