A person with knowledge of the decision says Krzyzewski has agreed to return as U.S. men's Olympic basketball coach. He was originally expected to step down but instead will attempt to lead the Americans to a third straight gold medal, the person tells The Associated Press on condition of anonymity because no official announcement has been made.
