Fans of Team USA basketball had become used to seeing the familiar face of Duke head coach Mike Krzyzewski roaming the sidelines in the Olympics and other international competition. After Coach K's retirement from coaching the national team, San Antonio Spurs coach Gregg Popovich was chosen to take over Team USA. One of his first choices for his staff was Warriors coach Steve Kerr, and Kerr spoke Tuesday about the privilege of being on Popovich's staff as the team prepares for the FIBA World Cup beginning later this month.
