Its record in international play answers that question. Even with a much smaller basketball-playing population than the United States, the Brasilians consistently compete with the U.S. internationally, and even beat the Americans in a friendly in March. Across the Atlantic, the typical European game is almost the opposite of the one in Brasil. A lot of people are quick to proclaim that European style as slow and lacking the physicality of play in the United States, but that is only one side of the story. While the above stereotypes may hold true, to some extent, there are other attributes that more than make up for them.
European players are extremely skilled at every position, both with and without the ball.
It is normal to see a post player moving like a guard, shooting three-pointers and handling the ball. Since everyone is being taught to do everything, the rigid classification by height commonly found in the U.S. is simply ignored. Some players may indeed be slow, but you are always in danger of being faked out by a myriad of different moves, and sometimes physically different moves, than are seen in the U.S. Deliberation and imposing a slower tempo are both tactics that American players and teams sometimes struggle with. For that reason, for the most part the scores are not very high. There is little emphasis on the fastbreak, and much more on post play.
