One of the nicer and more misunderstood guys to pass through Duke is Chris Burgess. He left after his sophomore year, apparently after some pressure from a family member who thought he should be more of a star at Duke than he was.
He went to Utah where he had an injury-riddled two years under the late Rick Majerus and then had an itinerant pro career, playing all over the world but never the NBA.
His recruitment was intense though as he was seen as the #1 player in his class and it came down to BYU - Burgess is Mormon - or Duke.
