#31 in the picture above is Sean Battier, not Cory Maggette. I assume the point of the picture was to show Coach Krzyzewski.
Maggette was found to have accepted money from a street agent named Myron Piggie, making him ineligible by rule to play amateur college basketball. To my knowledge neither he nor Duke were ever penalized by the NCAA. Maggette wore #22 at Duke.
My error - Maggette wore # 50 at Duke.
