Mike Krzyzewski had his fun coaching millionaires. College, he said, is where he belongs.

After a disappointing bronze medal as coach of the US team in the world championships, Coach K is back on Duke's campus.

"I'm happy with what I'm doing, coaching the Duke team," Krzyzewski said Wednesday. "I don't have a great desire to coach in the NBA. That isn't saying these guys weren't great. I just love what I do."
