Sitting side by side, they watched video of a scrimmage. Krzyzewski hit pause. "Look at your feet," he said. "They are in the wrong position."

Parker nodded. Krzyzewski stood and demonstrated the correct stance.

Moments later Krzyzewski stopped the tape again. "Look at your hands," he said. "They are not ready."

"I gotta change that," Parker said.

On the next sequence Coach K zeroed in on Parker's hips. They were turned in the wrong direction.

"This is about precision and doing physical things to create better habits," Krzyzewski said. "It's what the guys I coach in the summer do. Kobe and LeBron and Durant are precise."

After an hour Krzyzewski turned off the film. "I never realized I looked that bad," Parker said. Krzyzewski leaned in closer and looked into Parker's eyes. "It's not personal," he told him. "It's the truth."

Parker left the theater energized.

"In high school I used to watch highlights of myself in my living room," Parker says. "I basically focused on my scoring. Watching film with Coach is very different. It's intense. I came to Duke for experiences like this."
