Krzyzewski, who coached Okafor for one season, said people should not judge Okafor based solely on his most recent actions.
"Jah is one of the greatest kids ever. Ever, ever, ever, ever," Krzyzewski said following Duke's game against Indiana. "He did a couple of stupid things, and so knock him for it. Suspend him, but let's move on. Make him learn from it, but don't characterize him based on that. He's a special, special kid."
Okafor's two-game suspension came the same day a second video was released by TMZ showing him involved in a scuffle in Boston. The initial video from that night was posted last Thursday.
Okafor, who will turn 20 on Dec. 15, was caught on video engaging in a brawl with a man outside the nightclub in the early-morning hours last Thursday. The victim filed a report with the Boston Police Department, and police have urged any other possible victims from the second incident to come forward. The videos released by TMZ appear to show two separate scuffles.
"He got into a situation, and he made a mistake, but they also need to have security," Krzyzewski said. "When we are with the U.S. team, everybody has security because they're targets. But he's got to be smart, and he was not."
