Totally agree. Just to pick a specific example and add on a bit: Germany reorganized their nationwide soccer development system in the mid-2000s to be much more centralized, and that's widely considered to be one of the reasons they have risen in prominence recently (they are the current reigning World Cup champions, for instance).
Well, there was a really bad period in between then and now.
They finished last in their group in Euro 2000, and did quite badly in 2004 (though I don't remember specifics), and those were the results that motivated several changes (or, at least, moved some already-in-progress moves towards centralization forward).
