"I got better doing it," Krzyzewski said of his time as U.S. coach. "Just like a player gets better from doing it, we all got better. And that energizes you because it's like a teacher learning new material. I'm 66. I don't know how you're supposed to feel at 66. I never think of my age. ... But I feel energetic, passionate, wanting to achieve."
"Really it's just the opposite," Krzyzewski said. "I don't think anybody should coach the [Olympic] team unless they're still coaching. You've got to stay sharp. I'm coaching in the best league against the best competition and the best players that I can. Doing that, it becomes easier."
Asked to clarify if that meant he'd definitely coach at Duke through at least the 2015-16 season, the 66-year-old Krzyzewski said, "Obviously I'm not going to end before the Olympics."
