Mike Krzyzewski thought he was done with USA Basketball. He said he was done, too. "I know," Krzyzewski says now, "[that] I'm gonna coach for a number of years yet even though I'm an older guy." Turns out Krzyzewski wasn't sure how much coaching he wanted to do of any kind after the long grind in London that secured a second straight gold medal for Team USA only after a narrow, nervy escape against Spain in the championship game. After helping Team USA win two straight Olympic gold medals, there appeared little left for him to accomplish. He has made it clear here in Las Vegas that he would "never leave Duke," but he also conceded that "at some time you're going to stop coaching."
