To say that the reason the Euro's have beaten us in the WC's is because they have played together since they were 15 yr's old and all we had was a two week training camp is the height of arrogance and certainly denial that the world has caught up.
No, its the height of truth. And you may have been taught something trite like "put up or shut up", but that has little to do with the vagaries of real life. Its a nice motto for high school coaches teaching kiddies, but circumstances make all the difference. You take a dozen Serbain players who have never played together before and give them two weeks of training and see how well they do as a "team" out there in the WCs. On a similar note you take the Celtics in the Finals, have KG get hurt in Game 1, and you can say "put up or shut up" all you want, the injury would be an enormous factor. As it was for us when Webb wnet down. Or even Peja in that WCF.
It was the height of arrogance to assume that approach could continue to work in the face of the developing competence of the rest fo the basketball world. It is the height of intelligence to recognize that it could not and that all the chest puffing of Euro ballers over a result matching their carefully constructed teams, full of guys truly passionate about the WCs, with a random group of American stars trying to sell sneakers is what's pathetic. Its a yeah, yeah, whatever moment.
As an aside, the tough players you noted from Europe have been little players. We were talking bigs. There is a vast difference -- European little players often suffer from lack of defense, at least traditionally because of footspeed and an overreliance on zones, but they have not as a group been nearly as soft as the bigs. We saw a scrappy one in these Finals in Vujacic. Nor is a "soft" small player NEARLY the problem that a soft big player is. Your depend on your bigs to do all the things that a small player cannot -- rebound, block shots, defend the post and the rim, post up. For whatever reason (and that whatever is ruleset, coaching, culture) Euro ball has traditionally promoted skilled but soft
bigs, not littles. This is no huge secret in the basketball world. It is even sometimes a matter of pride and huffing and puffing from Euro ball fans. It is however a major problem once you try to bump those players up to a league full of bigger, tougher interior players.
So far as I can recall we are 0-fer forever on a Euro big winning a title as the main guy, or maybe even as a rotation guy. 0-fer forever on a Euro big being a top 5 rebounder. 0-fer forever on a Euro big being on any of the all-defensive teams. And there is a definitive connection -- KG, Shaq, Duncan, Wallace, Robinson, Rodman, Hakeem, Grant, Laimbeer, McHale etc. have won every title for the last 20 years. They've all been top rebounders, top defenders, top post players. Sooner or later its going to happen. But if your resume as a 6'11"+ player starts off with "good shooter" and "plays team ball" and does not prominently mention rebounding, defense, post play, then you are soft and ill suited to get it done in the NBA. I have been eagerly waiting the exception to that rule, the guy who will change that, for at least the last decade as the ebst European players have flooded into the league. I still have yet to see it.
