New York ? Mike Krzyzewski says he still hasn’t decided if he will return as U.S. basketball coach, even as a decision is planned for about a month from now. Krzyzewski led the Americans to the gold medal in the 2008 Olympics, and said Thursday the coaching job has been offered to him again. However, he said he didn’t want to make any decisions until after the NBA season ended, so he could talk to some players and assistants.
