Some pretty lazy, cheap shots here.
1. Anything involving Maggette occurred in high school, before matriculating to Duke.
2. If there is any concrete information about Lance Thomas out there, I haven't seen it. Just speculation by haters.
3. This one is especially ill-informed. You have a UNX MBA, correct? Many years ago, the AACSB would not give the Duke MBA accreditation because the undergrad management science program did not require enough hours of business courses. Rather than increase the # of business classes in the undergrad major, the university chose to drop the BA in management science altogether. The closest thing Duke has to an undergrad business major is the "Markets and Management" concentration in -- you guessed it -- the Sociology department. Nearly 25% of Duke Sociology majors assume managerial or administrative positions in banking, insurance, real estate, business services, agribusiness, manufacturing, brokerage and investment, wholesale trade, hotel management, private foundations, lobbying organizations, hospitals, and colleges.
