BW undergrad B-school ranking 2006

Businessweek just cooked out their inaugural ranking list of Best undergrad B-schools. Interestingly, I found no Harvard, Yale, Columbia, Brown, or Dartmouth in the list. My guess would be that those Ivy League schools do not have a so-called undergrad business degree for undergrads, rather just a major in business. At Michigan, only select sophomores could grasp a BBA degree beared big M through 2 year study at Ross B School.
