This conversation always seems to suggest some permanence if they do. Is it likely, given the population difference, growing availability of resources/higher youth competition levels, and increasing participation that the us at least has a period of time as the unanimous favorite going into best on best tournaments? I’d say yes. Will they be so much better than anyone that they can’t lose any one of them? Almost certainly not. If that time does come, does it mean they won’t be overtaken at some point? Absolutely not.
It’s the same reason when great young teams win a cup and people wonder how they’ll be beaten for the next half decade, but they never win 5 in a row. Obviously the cap is a factor that’s irrelevant for intl. i think the bigger factors are other teams rising, young players emerging, and most importantly, the unquantifiable mental element. When you’re chasing something, you have an idea of the bar you need to meet to get there. When you become the standard and wear the target, it’s nearly impossible to match the hunger of teams chasing you, and be able to raise your standard at or above the rate they are closing in on the one you set. Inevitably the crown is taken. It’s an eternal truth of humanity since the beginning of time for any throne, wealth, or trophy to be claimed.
