We had D'Asani over here long enough so that everybody knows how much he sucks
Guys don't be homers and look at what good NBA coaches do during games, how they adapt the tactics to the game at hand - we rarely see that in Euro games and even rarely to the extent it's present in the NBA. One of the most common complaints from Euro players is how difficult it is to learn all the sets and plays from the coach's playbook.
OTOH US coaches rarely work on the fundamental skills of their players. It starts in High School but good coaches (and programs) at that level are rare. After that fundamentals are often confounded with athleticism.
