Gregg Popovich succeeded Coach K as the coach of Team USA and while his approach is different, they have something key in common: they both have a military background.
Mike Krzyzewski famously attended West Point where he played for Bobby Knight; Popovich went to the Air Force Academy and was a serious candidate for the 1972 team that lost to the Soviets in a deeply controversial game.
Popovich, as much as anyone could be, is committed to the United States basketball team. He has a tougher job in many ways than Coach K did, primarily because so many talented players decided to take a pass or injured.
