NBA commissioner David Stern isn?t so sure about the new concept that had the Celtics, Minnesota, Toronto and Memphis hold their training camps in Europe.

?I?m not sure that they?re all that I wanted them to be, because it?s hard to move them and then to make sure that the teams have the opportunity to really train,? he said. ?Because that?s what they?re doing, they?re preparing.

?So I had this great idea. I take full responsibility for it. I?m not sure it?s the best idea I ever had. The more important thing is the games. To bring teams over and then to have them cloistered might seem anti-social, but I understand it because it?s very important for teams that are new and together to bond and also to practice.?
